# Vertical Short-Form

46 cards. These decide a shot: how it moves, how it cuts, and how it sits in time.

Every card carries what it is, what it does to the audience, where it works best, what to avoid, and the prompt written out in full.

### Which Of The Three Jobs Is This Doing

**Also called:** the vertical selector, the short-form fork, stop, hold, or spend  
**What it is:** The card at the head of the `vertical.` shelf. It describes no shot. It asks the three questions the shelf's own pair graph asks over and over — **which of the three jobs this card is doing, whether the piece is spending its point or withholding it, and what has to be true of the material before the card will work** — and hands back a named shortlist for each answer. The axes were not invented: they were read off the shelf's `Yields to:` conditions, and the conditions that repeated became the questions. Every card cited here is cited by id.  
**Effect on the audience:** None. This card never reaches the screen. It exists so that the device which does reach the screen was chosen against the job, the payoff and the footage you actually have, rather than picked because it is the one the editor already knows the keyboard shortcut for.  
**Used for and where it works best:** Answer the three questions **in order and out loud, one sentence each, before you open the shelf**. Answer one is a fact about the piece and eliminates most of the file. Answers two and three leave a shortlist of three to six. If you cannot answer question two — *is the point being spent now or held* — you do not yet have a short-form piece, you have a clip, and the shelf's whole retention half will not apply to it. Where two answers to question one fight for the same seconds, that is a piece trying to open and close at the same time, and one of them is `vertical.loop_point`.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vertical Micro-Drama, Meme / Comedy Edit, Commercial / TVC, Explainer, Kids Content | genres: all  
**Avoid when:** **The brief's aspect is horizontal.** A reel or feed video on Facebook or YouTube can be 16:9 as easily as 9:16, and the aspect is the brief's: a 16:9 feed piece takes its framing from the general shelves and its edge band from `comp.safe_areas`, not from this shelf. **You are reframing an existing horizontal master rather than composing a vertical piece.** There the shot was staged for another shape and the job is the conversion, not the choice — `vertical.action_descends` says so in its own `Avoid when:` and hands that case outward. Also **distrust axis three's third value entirely.** It is the value that decides where in the frame something may sit, and the three cards under it that carry actual measurements do not agree about the upper band; worse, **the card that owns the Instagram Reels and TikTok figures (Facebook's are on `vertical.facebook_safe_zones`) also carries a `Shelf life:` line saying those figures have already been wrong once and that other files copied the error.** This map points at that card and repeats nothing. A selector that quoted a band, a percentage or a margin would become the next copy of a value it cannot check, and this one therefore contains none.  
**Prompt:** `[Selector — produces no prompt. It returns card ids. The chosen card carries the prompt.]`

**The axes**

**Axis 1 — Which of the three jobs is this doing: stopping the scroll, holding the watch, or spending the last seconds?**
Asked first, because the shelf's pair graph has three almost separate components and this is the line between them. Almost every edge stays inside its own group: `vertical.cold_cut` to `vertical.text_hook` and `vertical.title_card_zero` to `vertical.text_hook` are both openings; `vertical.jump_cut` to `vertical.reframe` and `vertical.broll_burst` to `vertical.reframe` are both body; `vertical.loop_point`, `vertical.cliffhanger_cut` and `vertical.comment_bait` all route to `vertical.end_cta` and nowhere else. The conditions say the same thing in words: *"Calm or instructional; name the subject immediately"* (`vertical.cold_cut`), *"The opening needs a promise, not a label"* (`vertical.title_card_zero`), *"Emotional beat; change size, do not jump"* (`vertical.jump_cut`), *"Standalone video with no part two"* (`vertical.cliffhanger_cut`), *"The information has ended; close it"* (`vertical.loop_point`). The fourth value is the cards that have no position because they apply at every moment — they describe the frame rather than the timeline.

**Axis 2 — Is the piece spending its point or withholding it?**
Fourteen conditions turn on this and they are stated as facts about the payoff, not feelings about the viewer: *"The surprise is the pleasure; hide it"* (`vertical.result_first`), *"The reveal cannot match the promise"* (`vertical.curiosity_gap`), *"No payoff worth waiting for"* (`vertical.watch_till_end`), *"The payoff must not be spent early"* (`vertical.promise_beat`), *"No real planted detail to send them back"* (`vertical.loop_bait_ending`), *"No safe question to plant"* (`vertical.comment_bait`), *"No narrow group worth naming"* (`vertical.callout_hook`), *"No hard evidence; ask rather than assert"* (`vertical.contradiction_hook`), *"Drama; showing the length kills suspense"* (`vertical.progress_bait`). Their `Avoid when:` lines converge on one sentence: a promise larger than the thing promised is the only failure this shelf treats as permanent — *the audience will not believe you next time*, *the comments expose it fast*, *the count is the contract*. The third value is the large group that is neither, because it is a way of showing rather than a way of pacing.

**Axis 3 — What has to be true of the material before this will work?**
The largest condition cluster on the shelf and the one asked last, because it disqualifies rather than chooses. Four kinds, each stated plainly: a **source quality** the footage must already have — *"Low-resolution source will not take the crop"* (`vertical.reframe`), *"Camera or light will not hold a mask"* (`vertical.clone_effect`), *"No matching camera whip on both shots"* (`vertical.whip_transition`), *"Nothing available to cross the lens"* (`vertical.walk_past_cut`); a **second element** that must exist — *"Two figures in frame; stage in depth"* (`vertical.center_subject`), *"The near figure covers the reaction we need"* (`vertical.stacked_two_shot`), *"The source image is busy or moving"* (`vertical.green_screen_react`), *"You need to point into the image"* (`vertical.split_react`); **a band of the frame that something else may already own** — *"The frame cannot spare a permanent band"* (`vertical.caption_bar`), and the whole of `vertical.action_descends`, whose pair field hands the reserved top and bottom bands outward to `vertical.safe_zones` because *the band wins*; and a fourth value for the cards that ask nothing of the material at all.

| **A second thing that must exist — a figure, an image, a group, a real payoff** (twenty-five) | `vertical.duet` · `vertical.stitch` · `vertical.split_react` · `vertical.green_screen_react` · `vertical.stacked_two_shot` · `vertical.vertical_eyeline` · `vertical.comment_bait` · `vertical.loop_bait_ending` · `vertical.list_cards` · `vertical.countdown` · `vertical.progress_bait` · `vertical.contradiction_hook` · `vertical.callout_hook` · `vertical.number_hook` · `vertical.rewind_hook` · `vertical.curiosity_gap` · `vertical.result_first` · `vertical.watch_till_end` · `vertical.promise_beat` · `vertical.cliffhanger_cut` · `vertical.question_hook` · `vertical.start_mid_action` · `vertical.pattern_interrupt` · `vertical.cover_frame` · `vertical.stacked_split` |
| **A band of the frame something else may already own** (fourteen) | `vertical.safe_zones` · `vertical.text_safe_zone` · `vertical.captions` · `vertical.caption_bar` · `vertical.text_beyond_picture` · `vertical.text_hook` · `vertical.title_card_zero` · `vertical.pov_caption` · `vertical.center_subject` · `vertical.fill_frame` · `vertical.vertical_stack` · `vertical.face_first_frame` · `vertical.action_descends` · `vertical.facebook_safe_zones` |
| **Nothing — it works on whatever you shot** (seven) | `vertical.visual_hook` · `vertical.motion_hook` · `vertical.sound_hook` · `vertical.silent_first_second` · `vertical.talk_to_camera` · `vertical.pov_camera` · `vertical.end_cta` |

*A card appears once per axis. The answer is the intersection of the three shortlists, and it is normally three to six cards wide.*

**Two disputes this map reaches and does not settle.** Both live under axis three's third value, and neither has a row in `COLLISIONS.md`.

**The upper band of the 9:16 frame is claimed three times over.** `vertical.eyes_upper_third` puts the eyeline in the upper third and calls it the working rule for every talking head and vertical interview. `vertical.caption_bar` puts a permanent series band at the top and keeps it there for the whole piece. `vertical.safe_zones` says the top band belongs to the platform's interface, and it holds the figures for it, with Facebook's on `vertical.facebook_safe_zones`. `vertical.text_safe_zone` then defines the readable band as starting *just under the upper third*, which is a fourth statement about the same boundary. **Nothing routes any of these to any other.** `promo.super` does it correctly and is the model: its whole pair field is an authority yield to `vertical.safe_zones` on any 9:16 delivery. Read that card before you place anything, take the figure from the platform's own current page as that card itself instructs, and take no number from any other card. **Nothing here is settled and no figure is corrected.**

**The last frame of a vertical reel is claimed four times.** `vertical.end_cta` gives the last seconds to one spoken and written request, and to audio alone where the piece loops. `promo.end_card` describes a designed final static frame and then, in its own `Avoid when:`, refuses itself on a vertical reel in favour of the logo sitting on the last live shot. `promo.pack_shot` places itself at the end with its own hold. `promo.date_card` calls itself a final or near-final card. **Four cards, one frame, four different holds.** Take the answer from the brief.

---

**The default, and the one against it**

**The default is `vertical.text_hook` — a short line of type on the first frame — and it is measured, not asserted.** Three cards send a reader here, and unlike the card that looks like the default they send them for three unrelated reasons: `vertical.cold_cut` (*"Calm or instructional; name the subject immediately"*), `vertical.title_card_zero` (*"The opening needs a promise, not a label"*) and `vertical.visual_hook` (*"The image needs explaining to read"*). Wrong tone, wrong kind of text, and no self-explaining picture — three different failures, one destination. The shelf, asked where to fall back to when the opening is not working, falls back to putting the promise in words.

**The card that looks like the default is not one, and this is the trap that would have made the selector wrong.** `vertical.visual_hook` takes four inbound edges, more than anything else on the shelf, and **all four but one say the same thing**: `vertical.text_hook` (*"The picture is strong enough to hook alone"*), `vertical.motion_hook` (*"You do have a shocking image"*) and `vertical.silent_first_second` (*"A self-explaining image beats more text"*) are one condition in three wordings — *you have a strong image*. Only `vertical.face_first_frame` (*"Subject is a product or a place"*) is distinct. Four edges, two conditions. **In-degree measures how often the shelf runs out of options, not what it falls back on.** `vertical.result_first` collapses the same way: three edges, of which *"The reveal cannot match the promise"* and *"No payoff worth waiting for"* are the same sentence.

**The one against it is `vertical.action_descends`.** Nothing routes to it; it is named by no `Yields to:` on the shelf; and it is the only card here that treats the vertical frame's **height as something to stage into** rather than as a cropping problem to survive. Every other framing card on this shelf asks how to fit a horizontal idea into a tall box — `vertical.fill_frame` tightens, `vertical.reframe_169` crops, `vertical.tri_panel` stacks, `vertical.center_subject` centres. This one asks what only a tall box can do: put the fall, the drop, the descent on the axis the frame is long in. Its cost is stated and narrow — it needs a piece with movement in it, and it excludes itself from an interview, a talking head or a piece built from stills. And it is the only card on the shelf that hands its own frame position outward to the card that owns it, which is the behaviour every card under axis three's third value ought to have and only this one does. **Its near cousin against the grain is `vertical.vertical_stack`**, likewise never yielded to, and the only card that treats the frame as more than one picture at once rather than one picture cropped.

---

**The unasked**

**Twenty-seven of the sixty-three reachable cards are the target of no `Yields to:` field anywhere on this shelf.** They can be chosen but nothing ever sends you to them. By id:

`vertical.action_descends` · `vertical.before_after` · `vertical.stacked_split` · `vertical.callout_hook` · `vertical.caption_bar` · `vertical.cliffhanger_cut` · `vertical.clone_effect` · `vertical.cold_cut` · `vertical.comment_bait` · `vertical.cover_frame` · `vertical.face_first_frame` · `vertical.handheld_phone` · `vertical.jump_cut` · `vertical.loop_bait_ending` · `vertical.motion_hook` · `vertical.number_hook` · `vertical.pattern_interrupt` · `vertical.progress_bait` · `vertical.promise_beat` · `vertical.rewind_hook` · `vertical.shake_punct` · `vertical.sound_hook` · `vertical.start_mid_action` · `vertical.talk_to_camera` · `vertical.text_safe_zone` · `vertical.transition_on_beat` · `vertical.vertical_stack`

**And the shape of that list is the finding, not its length.** Take the cards that describe **where things may sit in the frame** rather than what happens in it, and count how many are on this list: `vertical.text_safe_zone`, `vertical.caption_bar`, `vertical.vertical_stack`, `vertical.action_descends`, `vertical.cover_frame` — and add the ones the map cannot carry at all because `PAIR-AUDIT.md` files them `additive`, which are `vertical.eyes_upper_third`, `vertical.foreground_layer`, `vertical.hook_stack`, `vertical.hook_window` and `vertical.beat_sync`. **Nearly every card that governs the geometry of the frame is either unreachable by the graph or excluded from it.** And that is precisely why the upper-band dispute above is unrouted: three cards claim one band, and there is not a single edge joining any two of them, because **the pair graph on this shelf is a graph of devices, and a statement about where a thing may sit is never an alternative to a device.** A reader comparing two cards is holding one moment; the cards that are about the whole frame at every moment cannot be compared to anything, so nothing ever points at them — including at the one card that would have told the reader the band is already taken.

The second thing the list shows: **the whole opening block that works on something other than a picture or a word is unasked** — `vertical.sound_hook`, `vertical.motion_hook`, `vertical.pattern_interrupt`, `vertical.start_mid_action`, `vertical.cold_cut`, `vertical.face_first_frame`. Every one of them yields outward and nothing yields inward. The shelf's hook graph is a two-node argument between `vertical.text_hook` and `vertical.visual_hook` — *words or picture* — with everything else hanging off the outside of it. Nothing on the shelf treats **the first sound** as a thing that can be chosen against the first image; the audio hook exists, routes away to `vertical.silent_first_second`, and is never routed to. The new card this shelf wants is the one that asks what the first second sounds like to the ninety per cent who have the volume off and the ten who do not, and answers for both at once; the nearest thing that exists, `vertical.silent_first_second`, records that split in its own `Avoid when:` — *do not turn the whole video into text; that kills the audio for the viewers who unmute* — without anything routing a reader there to read it.

`vertical.choose_the_job`

### Text Hook

**Also called:** opening caption hook, on-screen hook line  
**What it is:** A short line sits over the first frame, three to seven words, telling the viewer exactly what they get if they stay.  
**Effect on the audience:** It works through fast silent reading and buys the image time to be understood. The viewer decides in half a second.  
**Used for and where it works best:** Essential when the picture itself is ordinary: talking head, explainer, before and after. Place it in the upper third above the face, large, two lines maximum, and hold it at least three seconds so it can be read. In short documentary let it pose the question the video will answer.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Explainer, Video Essay, Commercial / TVC, Product Video / Motion Design, Meme / Comedy Edit, Vlog / YouTube Long-Form | genres: Science / Educational, Slice of Life, Comedy, Drama, True Crime, Historical / Biopic, Family  
**Avoid when:** A line that needs thinking, or a term the viewer does not know, usually loses the scroll, because the decision happens before the thought finishes; the exception is a specialist account whose audience already owns the term. Text that disappears in under a second is not read; it exists only for the person who made it.  
**Prompt:** `bold two line caption across the upper third of the vertical frame, held static over the opening shot`  
**Yields to:** `vertical.visual_hook` — The picture is strong enough to hook alone.  
`vertical.text_hook`

### Motion Hook

**Also called:** movement opener  
**What it is:** The opening frame already carries movement: a hand in motion, something falling, the camera travelling, an object driving toward the lens.  
**Effect on the audience:** The eye catches movement before detail, so a moving opening frame stops the scroll even when the content itself is simple.  
**Used for and where it works best:** Use it when you have no shocking image: have the camera already pushing in, or the subject entering frame rather than standing in it. In a vertical ad let the product enter the frame instead of starting inside it. In food and craft, open with the hand already working.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Commercial / TVC, Product Video / Motion Design, Music Video, Kids Content, Vertical Micro-Drama, Meme / Comedy Edit | genres: Action, Comedy, Slice of Life, Family, Sports Drama, Musical, Romance  
**Avoid when:** Aimless movement with no direction reads as noise. Do not let the motion hide the face or the product in the opening moment.  
**Prompt:** `the shot opens mid movement, subject entering frame from the left while the camera pushes in, no static beat at the start`  
**Yields to:** `vertical.visual_hook` — You do have a shocking image.  
`vertical.motion_hook`

### Question Hook

**Also called:** open loop question  
**What it is:** The video opens with a direct question, spoken or written, and the answer does not arrive until the middle or the end.  
**Effect on the audience:** It opens an unfinished loop in the viewer's head, and the brain dislikes an open loop enough to stay until it closes.  
**Used for and where it works best:** Strong for knowledge and history content: what happened in this place, why is this wall built this way, who built this. In an ad, ask about the problem your product solves. Let the image under the question be half the answer so curiosity rises.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Explainer, Video Essay, Heritage / Historical Documentary, Commercial / TVC, Vlog / YouTube Long-Form, News Report / Reportage | genres: Science / Educational, Heritage (civilisation-focused), Historical / Biopic, True Crime, Mystery / Whodunit, Slice of Life, Nature / Wildlife  
**Avoid when:** A question with an obvious or trivial answer sends the viewer straight back to scrolling. Asking and then failing to answer burns the account over time, because the next question is believed less; the exception is a series where the answer is openly held for the following part.  
**Prompt:** `open on the location with a large question caption across the top third, camera slowly pushing toward the detail that answers it`  
**Yields to:** `vertical.contradiction_hook` — The answer is obvious; break a belief instead.  
`vertical.question_hook`

### Result First Hook

**Also called:** payoff first, end first  
**What it is:** You open with the last shot: the finished thing, the room after the work, the plate ready, the piece cleaned, then go back to the beginning.  
**Effect on the audience:** It gives the viewer a visual promise: stay and you will see how we got here. Curiosity moves from the result to the road that led to it.  
**Used for and where it works best:** The backbone of transformation content: restoration, cleaning, building, make-up, cooking, design. In short documentary open on the finished lit object, then return to the dig or the research. Cut from the result to the start on a hard cut with no dissolve so the jump back in time reads.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Commercial / TVC, Product Video / Motion Design, Explainer, Vlog / YouTube Long-Form, Travel / Real Estate / Hospitality, Heritage / Historical Documentary | genres: Slice of Life, Science / Educational, Family, Heritage (civilisation-focused), Historical / Biopic, Nature / Wildlife, Comedy  
**Avoid when:** If the result is not impressive, do not spend it at the top. In a story whose pleasure is the surprise, revealing the result kills it.  
**Prompt:** `first shot is the finished result, clean and well lit, then hard cut to the raw starting state of the same subject`  
**Yields to:** `vertical.curiosity_gap` — The surprise is the pleasure; hide it.  
`vertical.result_first`

### Pattern Interrupt

**Also called:** scroll break, visual disruption  
**What it is:** Something in the frame breaks the eye's expectation: an odd colour, a wrong scale, a person staring straight down the lens, or a sharp sound on a sudden cut. It differs from The Break in the Pattern in composition, which builds a repeating pattern inside the frame and lets one element defy it: here the break is measured against the whole feed, not against the frame.  
**Effect on the audience:** It breaks the automatic scrolling state. The viewer wakes up because this frame is not like the fifty frames before it.  
**Used for and where it works best:** Use it at the top and again around second seven and second fifteen, where attention dips. Working moves: a full location change on one cut, a new character entering frame, a sudden size jump, or total silence inside loud audio. In meme edits it is the joke itself.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Meme / Comedy Edit, Vertical Micro-Drama, Commercial / TVC, Music Video, Vlog / YouTube Long-Form | genres: Comedy, Dark Comedy / Satire, Thriller / Suspense, Horror, Action, Surreal / Absurdist, Slice of Life  
**Avoid when:** An interrupt every two seconds turns the video into noise and drives the viewer out. If the break has nothing to do with the subject it reads as a cheap trick and it is remembered against you.  
**Prompt:** `sudden hard cut to a completely different colour palette and scale of the same subject, accompanied by one sharp sound hit`  
**Yields to:** `comp.pattern_break` — The break is inside the frame, not the feed.  
`vertical.pattern_interrupt`

### Half-Second Cold Cut

**Also called:** cold open cut, instant start  
**What it is:** The video opens on a shot shorter than half a second that cuts immediately to the next, with no intro and no run-up.  
**Effect on the audience:** It imposes a fast rhythm from the first instant and says without words that this video will not waste the viewer's time.  
**Used for and where it works best:** Suits lists, comparisons and the vertical trailer: three shots inside a second and a half give the full flavour of the content. In meme edits it lands the joke before the viewer is ready. Tie each cut to a sound hit.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Meme / Comedy Edit, Trailer / Teaser, Music Video, Vertical Micro-Drama, Commercial / TVC | genres: Action, Comedy, Dark Comedy / Satire, Thriller / Suspense, Musical, Sports Drama  
**Avoid when:** Wrong for calm or instructional content; it confuses the viewer before the subject is clear. If the shots cannot be read in half a second, the cold cut wastes them.  
**Prompt:** `three shots of under half a second each cut back to back on sound hits, then settle into a normal paced shot`  
**Yields to:** `vertical.text_hook` — Calm or instructional; name the subject immediately.  
`vertical.cold_cut`

### Start Mid-Action

**Also called:** in the middle, no run-up  
**What it is:** You delete the first two steps of any action and start on the third: the door is already open, the run has begun, the sentence is already half spoken.  
**Effect on the audience:** It makes the viewer chase the story instead of waiting for it, and that feeling of being slightly behind keeps them watching until they catch up.  
**Used for and where it works best:** The backbone of vertical micro-drama: open on the shouting, not on entering the house; on the slap, not on the reason for the argument. In an explainer, start on the step that contains the problem. In travel, start already inside the place, not still in the car.  
**Best in:** formats: Vertical Micro-Drama, Vertical Short-Form (Reels, Shorts, TikTok), Short Film, Meme / Comedy Edit, Soap Opera / Telenovela, Commercial / TVC | genres: Drama, Melodrama, Thriller / Suspense, Comedy, Romance, Crime / Procedural, Action  
**Avoid when:** If the viewer cannot tell who the characters are within two seconds, starting mid-action becomes confusion rather than tension. It also fails for content that depends on introducing a guest or a location.  
**Prompt:** `the scene is already in progress at frame one, the argument at its peak, handheld medium close-up, no establishing shot`  
**Yields to:** `vertical.title_card_zero` — A guest or location must be introduced.  
`vertical.start_mid_action`

### Sound Hook

**Also called:** audio hook, first note hook  
**What it is:** The first thing the viewer hears is a marker they recognise: the opening of a trending sound, a sharp hit, or a strong real-world sound such as a crack or a pour.  
**Effect on the audience:** The ear recognises faster than the eye, and a familiar sound creates instant familiarity that stops the scroll before the image is even understood.  
**Used for and where it works best:** Essential for dance, trend, food and product videos. Let the audio start on the very first frame with no silence before it. If you use a trending sound, enter at the part people recognise, not at the start of the track.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Music Video, Meme / Comedy Edit, Commercial / TVC, Product Video / Motion Design, Dance Film, Kids Content | genres: Musical, Comedy, Slice of Life, Family, Action, Romance  
**Avoid when:** A trending sound on content it does not suit makes the video look derivative. Do not start with loud music over an important line; the first sentence is lost.  
**Prompt:** `the recognisable part of the track starts exactly on frame one, cut the visual to its first beat`  
**Yields to:** `vertical.silent_first_second` — Music would bury the opening line.  
`vertical.sound_hook`

### Title Card At Zero Seconds

**Also called:** opening title overlay  
**What it is:** A short title appears over the first shot and holds for one to three seconds, as an overlay rather than a separate screen, and it never pauses the picture.  
**Effect on the audience:** It gives the viewer an instant label of what the video is about, and that quick categorisation lowers the drop-off in the first two seconds.  
**Used for and where it works best:** Useful for series: the same title position and typeface in every episode builds recognition. In vertical documentary put the site name and the period. Keep it in the upper third and clear of the top interface band.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vertical Micro-Drama, Heritage / Historical Documentary, Explainer, Video Essay, News Report / Reportage, Kids Content | genres: Heritage (civilisation-focused), Historical / Biopic, Science / Educational, Drama, True Crime, Family  
**Avoid when:** On a separate black screen it stops being a title and becomes an intro, which usually loses viewers in the first second; the exception is a channel whose black card is already a known signature. Do not write a long title of two and a half lines that cannot be read in the time available.  
**Prompt:** `short title overlay in the upper third of the opening shot, held three seconds, clean sans typeface, no separate title screen`  
**Yields to:** `vertical.text_hook` — The opening needs a promise, not a label.  
`vertical.title_card_zero`

### Rewind Hook

**Also called:** how we got here, flashback opener  
**What it is:** You open on the peak moment, then a fast rewind transition (reversed footage or a flash) takes the story back to its beginning.  
**Effect on the audience:** It creates one clear question: how did they get here. The reversed transition signals a jump back in time so plainly that it needs no explanation.  
**Used for and where it works best:** Excellent for micro-drama, incident stories and transformations: the crash first, then the morning of the same day. Keep the peak shot under two seconds so it does not spend the details. In short documentary, open on the discovery then go back to the search.  
**Best in:** formats: Vertical Micro-Drama, Vertical Short-Form (Reels, Shorts, TikTok), Short Film, Video Essay, Heritage / Historical Documentary, Meme / Comedy Edit | genres: Drama, Thriller / Suspense, Crime / Procedural, True Crime, Comedy, Melodrama, Action  
**Avoid when:** In a very short story the rewind is just a detour. Do not use it when the peak shot gives away the whole ending.  
**Prompt:** `open on the peak moment for one second, then a fast reversed rewind whip back to the calm start of the same day`  
**Yields to:** `vertical.result_first` — Very short story; hard cut back instead.  
`vertical.rewind_hook`

### Curiosity Gap

**Also called:** withheld reveal, hidden object hook  
**What it is:** Something in the frame is hidden, covered or cropped just outside the frame, and the video implicitly promises to reveal it later.  
**Effect on the audience:** The visual gap creates a low level of tension that only the reveal resolves, so the viewer stays to see it.  
**Used for and where it works best:** Use the closed box, the thing under the cloth, the shut door, the face just out of frame, the artefact still under dust. Schedule the reveal around second ten and no later. In advertising it works on the new shape of a product.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Commercial / TVC, Product Video / Motion Design, Vertical Micro-Drama, Heritage / Historical Documentary, Kids Content, Trailer / Teaser | genres: Mystery / Whodunit, Thriller / Suspense, Slice of Life, Family, Heritage (civilisation-focused), Science / Educational, Comedy  
**Avoid when:** If the reveal is smaller than the promise the viewer feels cheated and says so in the comments. Do not push the reveal to the final second of a long video.  
**Prompt:** `hero object stays covered by a cloth in the opening shots, hands hovering over it, the reveal saved for later`  
**Yields to:** `vertical.result_first` — The reveal cannot match the promise.  
`vertical.curiosity_gap`

### Contradiction Hook

**Also called:** myth buster opener  
**What it is:** You open with the common belief, then break it at once with an image or a line that proves the opposite.  
**Effect on the audience:** The contradiction creates a small knowledge imbalance, and the viewer stays to find out who is right, especially if they held the belief being broken.  
**Used for and where it works best:** Excellent for history, heritage and science: the famous wrong picture of a civilisation, or a working method everyone assumes is right. Let the first image show the common belief and the second shot show the evidence. Keep the evidence visual, not verbal.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Explainer, Video Essay, Heritage / Historical Documentary, Documentary Series, News Report / Reportage | genres: Science / Educational, Heritage (civilisation-focused), Historical / Biopic, True Crime, Mystery / Whodunit, Slice of Life  
**Avoid when:** Breaking a belief without real evidence usually turns the comments against you, because the specialist audience checks it first; the exception is an openly stated opinion that does not claim to be a fact. Do not manufacture a sensitive controversy just to farm views.  
**Prompt:** `first shot shows the popular assumption, hard cut to the real evidence in close-up with a short caption naming the correction`  
**Yields to:** `vertical.question_hook` — No hard evidence; ask rather than assert.  
`vertical.contradiction_hook`

### The Promise Beat

**Also called:** value promise, the setup line  
**What it is:** The shot that comes straight after the hook and tells the viewer exactly what they will get: the result, the information or the ending.  
**Effect on the audience:** It converts curiosity into an agreement. The viewer moves from a reflex stop to a decision to watch through.  
**Used for and where it works best:** Place it between second three and second five: a fast glimpse of the final result, or a line naming what will be solved. In short documentary make it the shot of the object or site the video is about. In an ad make it the product working, not the logo.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Commercial / TVC, Explainer, Product Video / Motion Design, Vertical Micro-Drama, Heritage / Historical Documentary, Corporate / Training | genres: Science / Educational, Slice of Life, Drama, Family, Heritage (civilisation-focused), Comedy  
**Avoid when:** A promise bigger than the content makes the viewer leave halfway and say so in the comments. Do not delay the promise past second seven.  
**Prompt:** `one second insert of the final result right after the hook, then cut back to the process from its first step`  
**Yields to:** `vertical.watch_till_end` — The payoff must not be spent early.  
`vertical.promise_beat`

### Jump Cut Every Two To Three Seconds

**Also called:** rolling jump cut, pace cut  
**What it is:** You cut the gaps out of the same take and cut back to the same person in almost the same frame, producing a visible jump every two to three seconds.  
**Effect on the audience:** It strips out every breath and hesitation so the talk becomes dense and fast, and the sense that no second is wasted prevents drop-off.  
**Used for and where it works best:** The first tool of talking head, advice and explainer content. Cut after each completed sentence, never mid word, and change the framing slightly on every cut so the jump reads as deliberate. In vlogs keep it to the talking passages and let the shot footage run at its natural pace.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vlog / YouTube Long-Form, Explainer, Video Essay, Meme / Comedy Edit, Corporate / Training, News Report / Reportage | genres: Science / Educational, Slice of Life, Comedy, Drama, Family, True Crime  
**Avoid when:** Cutting mid word or mid breath usually chops the speech and makes it hard to follow; the exception is a comic style where the chop itself is the rhythm. In an emotional beat the jump cut kills the feeling entirely.  
**Prompt:** `edit the talking take with a jump cut after every completed sentence, each cut on a slightly tighter or looser crop`  
**Yields to:** `vertical.reframe` — Emotional beat; change size, do not jump.  
`vertical.jump_cut`

### Punch In / Zoom Punch

**Also called:** crop cut, digital punch  
**What it is:** A cut from the same take to a crop twenty to forty percent tighter, with no camera move, so the viewer feels a jump forward.  
**Effect on the audience:** It puts visual stress on the word being said right now and resets attention without changing location.  
**Used for and where it works best:** Use it on the key sentence, on a number, and on the moment of reveal in talking content. In a vertical ad punch in on the user's face the instant they try the product. Best used once every six to ten seconds and no more.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vlog / YouTube Long-Form, Explainer, Commercial / TVC, News Report / Reportage, Video Essay, Corporate / Training | genres: Science / Educational, Slice of Life, Comedy, Drama, True Crime, Family  
**Avoid when:** Repeated punching with no reason makes the video feel needlessly anxious. If the take was shot at low resolution, the crop exposes the noise.  
**Prompt:** `hard cut to a thirty percent tighter crop of the same take on the key word, no camera movement, no dissolve`  
**Yields to:** `vertical.snap_zoom_word` — Comedy word needs an exclamation, not a reset.  
`vertical.punch_in`

### Snap Zoom On The Word

**Also called:** whip zoom, punch zoom  
**What it is:** A very fast zoom of four to six frames that stops dead, timed to the syllable of the important word.  
**Effect on the audience:** It does what raising your voice does in speech, and the abrupt stop creates a visual exclamation mark.  
**Used for and where it works best:** Best for comedy, memes and sharp commentary: zoom into the face on the exact frame of the punch word. Tie it to a short sound hit. In advertising use it on the price or on the single feature you want remembered.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Meme / Comedy Edit, Vlog / YouTube Long-Form, Commercial / TVC, Sitcom / Multi-Cam Comedy, Video Essay | genres: Comedy, Dark Comedy / Satire, Slice of Life, Family, Action, Sports Drama  
**Avoid when:** Two snap zooms in a row cancel each other and become irritating. In serious or documentary content it destroys the tone.  
**Prompt:** `five frame snap zoom into the face landing on the stressed word, hard stop, single percussive sound hit`  
**Yields to:** `vertical.punch_in` — Serious or documentary tone; cut, do not zoom.  
`vertical.snap_zoom_word`

### The Re-Frame

**Also called:** crop variation, size rotation  
**What it is:** You take one long take and pull three or four different sizes out of it with digital cropping, then alternate between them in the edit.  
**Effect on the audience:** It gives the feel of multi-camera coverage from a single camera and prevents visual boredom without changing the content.  
**Used for and where it works best:** Essential for the one-person crew: shoot at high resolution then crop a medium, a close and an extreme close. Change size with every new idea in the speech. Very useful for explainers and for vertical interviews cut out of a wide original.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vlog / YouTube Long-Form, Interview / Video Podcast, Explainer, News Report / Reportage, Corporate / Training, Video Essay | genres: Science / Educational, Slice of Life, Drama, Comedy, True Crime, Family  
**Avoid when:** Over-cropping a low resolution source destroys the image. Do not change size every second; that is jitter, not variety.  
**Prompt:** `cut between a medium, a close-up and an extreme close-up cropped from the same locked take, changing size on each new idea`  
**Yields to:** `vertical.broll_burst` — Low-resolution source will not take the crop.  
`vertical.reframe`

### B-Roll Burst

**Also called:** insert burst, cutaway volley  
**What it is:** Three or four very short cutaways are laid over the continuous audio, one after the other, then the edit returns to the main shot.  
**Effect on the audience:** It refreshes the picture without breaking the narration and leaves the viewer feeling they saw a lot in very little time.  
**Used for and where it works best:** Use it whenever the narration describes something: every named thing becomes a shot. In vertical and heritage documentary lay three macro shots of carving or craft under a single line. In travel place the burst around second ten where attention dips.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vlog / YouTube Long-Form, Travel / Real Estate / Hospitality, Heritage / Historical Documentary, Explainer, News Report / Reportage, Corporate / Training, Commercial / TVC | genres: Heritage (civilisation-focused), Historical / Biopic, Science / Educational, Nature / Wildlife, Slice of Life, Family, True Crime  
**Avoid when:** Cutaways that do not serve the line read as padding and the viewer feels the filler. Keep the burst under three seconds or the thread of the narration is lost.  
**Prompt:** `three one second inserts of the described detail cut back to back under the continuous voice over, then return to the main shot`  
**Yields to:** `vertical.reframe` — No cutaway genuinely serves the line.  
`vertical.broll_burst`

### Loop Point / Seamless Loop

**Also called:** perfect loop, invisible loop  
**What it is:** The last frame matches the first in composition, movement and sound, so when playback repeats the seam is invisible.  
**Effect on the audience:** It multiplies watch time with no extra content, because the viewer goes around once or twice before noticing.  
**Used for and where it works best:** Shoot the opening and closing shots in the same place, at the same size, with the same direction of movement. Ideal for dance, product, landscape and craft. In an ad return the product to its exact opening position so the loop closes.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Product Video / Motion Design, Music Video, Dance Film, Commercial / TVC, Kids Content, Travel / Real Estate / Hospitality, AI-Generated Clip | genres: Musical, Slice of Life, Family, Nature / Wildlife, Comedy, Romance  
**Avoid when:** A loop on a video whose information has ended becomes annoying and pushes the viewer out irritated. If the audio does not loop with the picture, the seam is exposed.  
**Prompt:** `final shot matches the opening shot exactly in framing and direction of movement so the video repeats without a visible seam`  
**Yields to:** `vertical.end_cta` — The information has ended; close it.  
`vertical.loop_point`

### Loop-Bait Ending

**Also called:** rewatch bait, hidden detail ending  
**What it is:** The video ends with a line or an image that sends the viewer back to the start: did you notice the thing in the background, watch the left hand.  
**Effect on the audience:** It turns one view into two or three, which is one of the strongest signals a platform reads.  
**Used for and where it works best:** It needs a real detail planted at the start: a hand, a shadow, a sound, a word written on a wall. Suits mystery, comedy and historical content with a real detail to spot. Keep the closing line short and specific.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Meme / Comedy Edit, Vertical Micro-Drama, Heritage / Historical Documentary, Video Essay, Kids Content | genres: Mystery / Whodunit, Comedy, Thriller / Suspense, Heritage (civilisation-focused), Historical / Biopic, Slice of Life, Family  
**Avoid when:** If the detail is not really there the comments expose it fast. Do not repeat it in every video; it wears out and the audience starts ignoring it.  
**Prompt:** `final shot holds on the frame that contains the planted detail with a short caption telling the viewer to watch again`  
**Yields to:** `vertical.loop_point` — No real planted detail to send them back.  
`vertical.loop_bait_ending`

### Cliffhanger Cut

**Also called:** part one ending, to be continued cut  
**What it is:** The video stops precisely before the answer or the result, ending on a face or on a half completed movement.  
**Effect on the audience:** It leaves the tension open, sending the viewer to the comments or to the profile to look for part two, which lifts engagement and not just watch time.  
**Used for and where it works best:** The backbone of serialised content and vertical micro-drama: every part ends on a new question. Cut on an incoming movement, never on stillness. Make sure part two is actually posted or you lose the trust.  
**Best in:** formats: Vertical Micro-Drama, Vertical Short-Form (Reels, Shorts, TikTok), Soap Opera / Telenovela, Documentary Series, Video Essay, Meme / Comedy Edit | genres: Drama, Melodrama, Thriller / Suspense, Crime / Procedural, Romance, True Crime, Mystery / Whodunit  
**Avoid when:** A cliffhanger on a standalone video leaves the audience feeling cheated. Hung on a trivial piece of information it usually reads as a trick, because the payoff has to be worth the wait; the exception is a comic anticlimax that is itself the joke.  
**Prompt:** `end the shot on the face one frame before the answer is spoken, cut to black on an incoming movement`  
**Yields to:** `vertical.end_cta` — Standalone video with no part two.  
`vertical.cliffhanger_cut`

### Beat Sync

**Also called:** cutting to the grid, beat mapping  
**What it is:** You build the entire edit on the beat grid of the chosen track: every cut lands on a beat and every shot length is a multiple of the beat.  
**Effect on the audience:** It makes the video feel made for the track rather than stuck onto it, and because the body responds to rhythm the viewer stays.  
**Used for and where it works best:** Mark the beats on the timeline first, then distribute the shots onto them. This is the difference between a reel that looks professional and one that looks random. Best for travel, dance, fashion and product. In talking content, cut on sentence ends but keep them inside the same grid.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Music Video, Dance Film, Fashion Film, Travel / Real Estate / Hospitality, Commercial / TVC, Product Video / Motion Design, Meme / Comedy Edit | genres: Musical, Action, Slice of Life, Romance, Comedy, Sports Drama  
**Avoid when:** Syncing every single shot to a beat with no exception becomes mechanical and tiring. Let one longer shot sit between groups so the eye can breathe.  
**Prompt:** `cut every shot exactly on the beat of the track, shot lengths as multiples of the beat, one longer shot every eight beats`  
`vertical.beat_sync`

### Transition On The Beat

**Also called:** beat transition, hit transition  
**What it is:** The transition itself (a wipe, a flash, a spin) ends exactly on the beat, so the movement breaks on the same instant as the sound.  
**Effect on the audience:** It makes the transition read as part of the music rather than an applied effect, and gives a rhythmic satisfaction that drives rewatches.  
**Used for and where it works best:** End the transition on the beat, not start it there; that is the working rule. Best used when the location, the wardrobe or the idea changes. In travel use a body wipe landing on the beat; on product use a short flash.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Music Video, Dance Film, Travel / Real Estate / Hospitality, Fashion Film, Meme / Comedy Edit, Commercial / TVC | genres: Musical, Slice of Life, Romance, Comedy, Action, Sports Drama  
**Avoid when:** A complex transition on every beat makes the video look like a template pack. A transition longer than half a second loses the beat that follows it.  
**Prompt:** `the wipe completes exactly on the downbeat, six frames long, matched to a movement inside the frame`  
`vertical.transition_on_beat`

### Freeze Frame Plus Text

**Also called:** stop and label, pause card  
**What it is:** The picture freezes on a single frame with text, an arrow or a circle stamped over it, then the motion resumes. It differs from Freeze Frame With Text in the time chapter, which stamps a character's name as an introduction card: here the freeze is a teaching tool that marks a detail.  
**Effect on the audience:** It stops time and gives the viewer a chance to read and to see the detail without pausing themselves.  
**Used for and where it works best:** Ideal for analysis and teaching: freeze on the moment of the mistake and ring it. In heritage documentary freeze on the relief and label its parts. In sport freeze on the contact. Hold for one to two seconds so it can be read.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Explainer, Video Essay, Sports Broadcast / Sports Film, Heritage / Historical Documentary, News Report / Reportage, Corporate / Training, Meme / Comedy Edit | genres: Science / Educational, Sports Drama, Heritage (civilisation-focused), Historical / Biopic, True Crime, Comedy  
**Avoid when:** A freeze too short to read is just a blink. Too many freezes break the flow and make the video feel like a dull lesson.  
**Prompt:** `freeze the frame on the key moment for one and a half seconds with a circle and short label over the detail, then resume`  
**Yields to:** `time.freeze_frame_text` — The stamp introduces a character, not a detail.  
`vertical.freeze_text`

### Shake And Glitch Punctuation

**Also called:** camera shake, digital glitch accent  
**What it is:** A short frame shake or a few frames of digital glitch placed on a specific moment, working like an exclamation mark.  
**Effect on the audience:** It grabs attention suddenly and suggests shock or malfunction, especially when it arrives with a sharp sound.  
**Used for and where it works best:** Use it in memes, suspense and mystery content: on the shocking word, on the appearance of the strange thing, on the turn to the opposite idea. Keep it to three to six frames. In advertising put it on the problem, never on the product.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Meme / Comedy Edit, Trailer / Teaser, Vertical Micro-Drama, Music Video, Video Essay | genres: Horror, Thriller / Suspense, Dark Comedy / Satire, Comedy, Mystery / Whodunit, Cyberpunk, Psychological Horror  
**Avoid when:** Shake on every shot wrecks the image, tires the eye and looks amateur. In formal or heritage content it breaks the dignity of the material.  
**Prompt:** `four frames of hard camera shake with a digital glitch and a sharp noise hit on the shock moment, then clean image`  
**Yields to:** `vertical.freeze_text` — Formal or heritage material; freeze, do not shake.  
`vertical.shake_punct`

### Duplicate / Clone Effect

**Also called:** twin shot, clone edit  
**What it is:** The same person appears two or more times in one frame, shot on a locked camera with the takes joined by a static mask.  
**Effect on the audience:** It creates a simple, legible surprise that makes the viewer stop and replay to work out how it was done.  
**Used for and where it works best:** Strong for comedy, for a dialogue between two characters played by one person, and for teaching when comparing two methods. Lock the camera completely and do not change the light between takes. Put the join line in an empty part of the background.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Meme / Comedy Edit, Vertical Micro-Drama, Music Video, Commercial / TVC, Explainer | genres: Comedy, Dark Comedy / Satire, Slice of Life, Drama, Fantasy / Epic, Surreal / Absurdist  
**Avoid when:** If the camera drifts at all, the mask line shows and the trick collapses. Avoid it in a scene with changing light such as moving sun.  
**Prompt:** `locked off vertical shot, the same performer appears on both sides of the frame, static split mask, identical lighting in both takes`  
**Yields to:** `vertical.clap_transition` — Camera or light will not hold a mask.  
`vertical.clone_effect`

### Duet

**Also called:** side by side response, split response  
**What it is:** Your video plays beside another person's video in the same screen, both running at once and sharing the audio.  
**Effect on the audience:** It creates a conversation between two people who were never in the same room and ties your content to the original clip's audience.  
**Used for and where it works best:** Best for responses, joint singing, commentary and comparison. Shoot yourself at the same height and framing as the original so the two read as one world. Keep your reaction visible on the face even when you are not speaking.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Meme / Comedy Edit, Music Video, Kids Content, Vlog / YouTube Long-Form | genres: Comedy, Musical, Slice of Life, Family, Dark Comedy / Satire, Romance  
**Avoid when:** A duet with a clip that does not serve your content dilutes your identity. Do not talk over the important lines of the original; both are lost.  
**Prompt:** `two vertical panels side by side, your performance matched in eye height and framing to the original clip`  
**Yields to:** `vertical.stitch` — Must not talk over the original's lines.  
`vertical.duet`

### Stitch

**Also called:** quote and reply, clip then respond  
**What it is:** You take a short clip from someone else's video as your opening, then your own video continues from that exact point.  
**Effect on the audience:** It borrows a hook that is already proven, and the switch from their voice to yours reads as a direct reply.  
**Used for and where it works best:** Use it for corrections, answers and additions: take the question or the wrong claim, then answer. Keep the borrowed clip under three seconds and start your reply immediately. Useful in science and history content for correcting a widespread claim.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Video Essay, Explainer, Meme / Comedy Edit, News Report / Reportage, Vlog / YouTube Long-Form | genres: Science / Educational, Heritage (civilisation-focused), Historical / Biopic, Comedy, True Crime, Political Thriller, Slice of Life  
**Avoid when:** A long borrowed clip makes the video theirs rather than yours. Do not use it to mock a private individual; it turns into bullying and it comes back on you.  
**Prompt:** `open with a two second borrowed clip then hard cut to your own framing answering the same question`  
**Yields to:** `vertical.duet` — The borrowed clip must run at length.  
`vertical.stitch`

### Whip Transition

**Also called:** whip cut, motion blur transition  
**What it is:** A very fast movement at the end of one shot and a matching movement at the start of the next, with the cut placed at the blurriest frame.  
**Effect on the audience:** It hides the cut completely so the viewer feels carried through one continuous space, which protects the flow in vertical.  
**Used for and where it works best:** Use it when the place or the time changes in travel and daily content. In vertical, whipping up or down works better than left or right because it follows the shape of the frame. Tie it to a short air whoosh.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Travel / Real Estate / Hospitality, Vlog / YouTube Long-Form, Music Video, Commercial / TVC, Dance Film, Wedding / Event Film | genres: Slice of Life, Adventure, Musical, Romance, Comedy, Action  
**Avoid when:** If the whip directions do not match between the two shots the illusion breaks and it reads as a pasted effect. Too many in one video is dizzying.  
**Prompt:** `fast upward whip at the end of the shot cutting on the blur into a matching upward whip that settles on the new location`  
**Yields to:** `vertical.walk_past_cut` — No matching camera whip on both shots.  
`vertical.whip_transition`

### Subject Centred

**Also called:** dead centre framing, vertical centring  
**What it is:** The subject sits dead centre across the width instead of on a horizontal third, because the vertical frame is narrow to begin with.  
**Effect on the audience:** It reads as stable and strong and stops the subject feeling squeezed to the edge, which matters because the sides get cropped in different placements.  
**Used for and where it works best:** The default rule for every talking head, every product demo and every vertical dance piece. Get your variety from height and size, not from sliding left and right. Break the centre only to clear space for text or for something about to enter frame.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vertical Micro-Drama, Commercial / TVC, Product Video / Motion Design, Kids Content, Music Video, Dance Film, Vlog / YouTube Long-Form | genres: Slice of Life, Comedy, Family, Musical, Drama, Science / Educational  
**Avoid when:** Absolute centring on every shot makes the video feel rigid. Do not centre when the character is looking to one side; they need looking room.  
**Prompt:** `vertical framing with the subject dead centre across the width, symmetrical background, camera locked`  
**Yields to:** `vertical.stacked_two_shot` — Two figures in frame; stage in depth.  
`vertical.center_subject`

### Eyes In The Upper Third

**Also called:** eyeline height, vertical headroom rule  
**What it is:** The eyeline sits in the upper third of the vertical frame, with the body and the hands filling the rest below.  
**Effect on the audience:** It keeps the face in the area the eye reaches first and leaves room below for captions without covering anything important.  
**Used for and where it works best:** The working rule for every talking head and vertical interview. Putting the eyes in the middle wastes half the frame on the ceiling. In micro-drama keep the standing character's eyeline at the same height across shots so the dialogue links.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vlog / YouTube Long-Form, Interview / Video Podcast, Vertical Micro-Drama, News Report / Reportage, Explainer, Commercial / TVC | genres: Slice of Life, Drama, Comedy, Science / Educational, True Crime, Family  
**Avoid when:** An eyeline hard against the top edge makes the composition suffocating. An eyeline below the middle leaves dead ceiling and shrinks the face. While a hook caption sits over the face (`promo.ugc_text_hook_face`), the caption takes the top of the safe band and the eyeline drops just below it for those seconds, never below the middle.  
**Prompt:** `vertical medium shot with the eyeline on the upper third line, hands visible in the lower half, clean background`  
`vertical.eyes_upper_third`

### Vertical Eyeline

**Also called:** up and down eyeline, stacked look  
**What it is:** Instead of two characters trading looks left and right, one looks up and the other looks down, because the frame is tall rather than wide.  
**Effect on the audience:** It solves the vertical dialogue problem: the cut stays legible and the relationship between the two is carried by height instead of side.  
**Used for and where it works best:** Essential in micro-drama: the standing character looks down, the seated one looks up, and you keep that difference on every cut. Use it for power and weakness: the boss above, the employee below. With a child and an adult it works naturally with no acting required.  
**Best in:** formats: Vertical Micro-Drama, Vertical Short-Form (Reels, Shorts, TikTok), Soap Opera / Telenovela, Kids Content, Commercial / TVC, Short Film | genres: Drama, Melodrama, Romance, Crime / Procedural, Family, Comedy, Thriller / Suspense  
**Avoid when:** Putting both at the same height looking the same way breaks the sense that they share a space. Do not over-angle the tilt or the face distorts.  
**Prompt:** `vertical two shot coverage, the standing character framed looking down and the seated character looking up, matched heights on every cut`  
**Yields to:** `vertical.stacked_two_shot` — The exchange fits one frame in depth.  
`vertical.vertical_eyeline`

### Foreground Layer

**Also called:** vertical depth cue, near element framing  
**What it is:** A close element sits at the bottom or the edge of the frame: a hand, a page, a plant, the edge of a table, held out of focus.  
**Effect on the audience:** It gives depth to a vertical frame that is flat by nature and makes the shot feel photographed rather than merely captured.  
**Used for and where it works best:** Use it when you cannot move in the space: place something near the lens at the bottom and keep the subject centred. In heritage documentary use the edge of a wall or a column as the near layer over the temple. On product, let a hand in the foreground give scale.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vertical Micro-Drama, Heritage / Historical Documentary, Travel / Real Estate / Hospitality, Product Video / Motion Design, Music Video, Wedding / Event Film | genres: Heritage (civilisation-focused), Historical / Biopic, Drama, Romance, Slice of Life, Nature / Wildlife, Thriller / Suspense  
**Avoid when:** A large foreground element that covers the subject or distracts is a loss. If it sits in the same focus plane it stops being a layer and becomes an obstruction.  
**Prompt:** `vertical shot with an out of focus foreground element along the bottom edge and the subject sharp in the middle`  
`vertical.foreground_layer`

### Stacked Two-Shot

**Also called:** depth two shot, near and far staging  
**What it is:** Instead of placing the two side by side, one is near the lens low in the frame and the other further away and higher up.  
**Effect on the audience:** It solves the narrow width of vertical and hands you a dramatic relationship for free: the near figure dominates, the far one is under pressure.  
**Used for and where it works best:** The backbone of dialogue coverage in micro-drama: keep a back or a shoulder in the foreground and the important face clear behind it. Swap who is near when the power in the scene changes. Use a wide aperture so the two faces separate.  
**Best in:** formats: Vertical Micro-Drama, Vertical Short-Form (Reels, Shorts, TikTok), Soap Opera / Telenovela, Short Film, Commercial / TVC, Kids Content | genres: Drama, Melodrama, Crime / Procedural, Thriller / Suspense, Romance, Comedy, Family  
**Avoid when:** If both are the same size at the same height the frame reads as crowded and unclear. The near figure covering the far one's face usually costs you the exchange, because we lose the reaction we came for; the exception is when hiding that face is the point of the shot.  
**Prompt:** `vertical two shot staged in depth, one shoulder near the lens low in frame, the second face sharp higher and further back`  
**Yields to:** `vertical.vertical_eyeline` — The near figure covers the reaction we need.  
`vertical.stacked_two_shot`

### Held-Phone Realism

**Also called:** selfie realism, phone camera look  
**What it is:** The shot is made to look like it came from a phone in someone's hand: natural shake, a wide lens up close, available light.  
**Effect on the audience:** It reads as instantly honest because it is the same look the viewer's own footage has, so the content feels real rather than advertised.  
**Used for and where it works best:** The basis of user content, of ads built to look like it, and of realistic micro-drama: let the frame breathe slightly and skip the perfect stabiliser. Shoot at natural hand height rather than on a tripod. In documentary keep it for the personal passages only.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Commercial / TVC, Vertical Micro-Drama, Vlog / YouTube Long-Form, Mockumentary, Meme / Comedy Edit, Product Video / Motion Design | genres: Slice of Life, Comedy, Drama, Romance, Verite / Observational, Found Footage, Family  
**Avoid when:** Exaggerated fake shake tires the eye and reads as acting. Do not use it for premium content or a luxury product; it lowers the perceived value.  
**Prompt:** `handheld phone style vertical shot, slight natural sway, wide lens close to the face, available light, no stabiliser`  
**Yields to:** `vertical.center_subject` — Premium content or luxury product.  
`vertical.handheld_phone`

### 16:9 To 9:16 Reframe

**Also called:** horizontal to vertical conversion, pan and scan vertical  
**What it is:** You take horizontal footage and turn it vertical by cropping and moving: enlarging on the important area and sliding the frame with the action.  
**Effect on the audience:** It rescues existing material for vertical, but it loses part of the original composition so the loss has to be compensated.  
**Used for and where it works best:** Use it for interview clips, documentary and archive: crop onto the speaker, and when two people are in frame stack them vertically instead. Move the crop slowly and with the action, never randomly. If the shot is very wide, convert it into a still with a slow push instead.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Documentary Series, News Report / Reportage, Interview / Video Podcast, Video Essay, Heritage / Historical Documentary, Sports Broadcast / Sports Film | genres: True Crime, Science / Educational, Heritage (civilisation-focused), Historical / Biopic, Political Thriller, Sports Drama, Nature / Wildlife  
**Avoid when:** A crop that cuts the head or removes half the information ruins the shot. Do not trust automatic reframing on shots with more than one person; it jumps between faces.  
**Prompt:** `reframe the wide shot to 9:16 centred on the speaker, slow deliberate crop moves that follow the action`  
**Yields to:** `vertical.tri_panel` — The wide's full width must survive.  
`vertical.reframe_169`

### Tri-Panel Split Of A Wide Shot

**Also called:** stacked thirds, triptych vertical  
**What it is:** You divide one horizontal shot into three crops and stack them in the vertical frame, so the whole wide shot is visible as three bands.  
**Effect on the audience:** It preserves the width of the original view without shrinking it, and gives a designed look instead of a small strip floating in black.  
**Used for and where it works best:** Ideal for landscapes, architecture and wide archive: a ziggurat, a city, a long wall. Keep all three bands moving in the same direction so the eye reads them as one scene. Useful for wide sports plays as well.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Heritage / Historical Documentary, Travel / Real Estate / Hospitality, Video Essay, Sports Broadcast / Sports Film, Documentary Series, News Report / Reportage | genres: Heritage (civilisation-focused), Historical / Biopic, Nature / Wildlife, Sports Drama, Science / Educational, Adventure  
**Avoid when:** When fast action crosses between the bands the eye loses the thread. Do not use it for more than one or two shots in a video.  
**Prompt:** `split the wide shot into three horizontal bands stacked in the 9:16 frame, all bands moving in the same direction`  
**Yields to:** `vertical.reframe_169` — Fast action crosses between the bands.  
`vertical.tri_panel`

### The Stacked Split Screen

**Also called:** top-and-bottom split, stacked panels, the vertical split for two places
**What it is:** The 9:16 frame divided into two horizontal panels, one above the other, each holding a different place or a different event at the same moment and both playing at once. It is the vertical form of the side-by-side split screen: in a tall, narrow frame two side-by-side panels are each too narrow to read - `vertical.split_react` says the same of its own layout - so the panels stack. Each panel is the frame's full width and half its height, which is close to square, and that is the shape each one is composed for.
**Effect on the audience:** Two places held in one frame at one instant. The viewer compares instead of following, and whatever happens in one panel is read against the other; nothing cuts away, so the tension runs continuously rather than in pulses.
**Used for and where it works best:** The vertical version of the two dramatic splits on the scene shelf: two events in the same moment, one approaching and the other unaware (`scene.split_screen_depalma`), and a call between two people in different places (`scene.split_screen_phone_call`). Both of those cards say it in their own `Avoid when:` - in vertical, stack the panels top and bottom. The relationship across the seam reads up and down rather than left and right, so the upper figure looks down and the lower figure looks up: the stacked form of `vertical.vertical_eyeline`. Keep each panel's subject clear of the platform's reserved bands, which fall across the top of the upper panel and the bottom of the lower one; `vertical.safe_zones` holds the figures, and `vertical.facebook_safe_zones` holds Facebook's.
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vertical Micro-Drama, Commercial / TVC, Music Video, Trailer / Teaser | genres: Thriller / Suspense, Horror, Crime / Procedural, Romance, Drama, Comedy, Heist
**Avoid when:** The two panels are not happening at the same moment, or are not connected - then the split is decoration, which is the limit the side-by-side splits state for themselves. And stay at two panels for a story: the package's moving split screen, `sig.split_screen_tracking`, warns that past two the viewer's attention shatters, and in a vertical frame each extra band also leaves a panel too short to hold a face and a gesture.
**Prompt:** `vertical 9:16 frame split into two stacked panels, upper panel a woman at a kitchen window looking down, lower panel a man in a phone box looking up, matched framing size and consistent grade, a thin clean seam between them`
**Yields to:** `vertical.split_react` — The lower panel is commentary on a source, not a second place or event.
`vertical.stacked_split`

### Before / After

**Also called:** transformation split, then and now  
**What it is:** The exact same framing is shown in two states, before the work and after it, joined by a straight cut. It differs from the Before / After Wipe, where a line travels across the frame revealing the new state over the old one with no cut at all.  
**Effect on the audience:** It provides instant visual proof that needs no words, and the difference itself is the pleasure. The strongest form of proof in short-form.  
**Used for and where it works best:** The basis of restoration, cleaning, make-up, design and construction content. The camera must be in the same position with the same lens and the same light or the comparison collapses. In heritage documentary use it between the site today and its reconstruction.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Commercial / TVC, Product Video / Motion Design, Explainer, Heritage / Historical Documentary, Corporate / Training, Travel / Real Estate / Hospitality | genres: Slice of Life, Science / Educational, Heritage (civilisation-focused), Historical / Biopic, Family, Nature / Wildlife  
**Avoid when:** Changing the light or the angle between the two states makes the comparison a visual lie. Do not put the after before the before; the order confuses the read.  
**Prompt:** `identical locked vertical framing shown twice, the before state then a hard cut to the after state, same light and lens`  
**Yields to:** `promo.before_after_wipe` — A travelling line joins the states, no cut.  
`vertical.before_after`

### End-Screen Call To Action

**Also called:** closing CTA, final card  
**What it is:** The last two seconds carry one clear request: follow, watch part two, comment a specific word, try the product.  
**Effect on the audience:** It converts a view into an action. Without an explicit request most viewers forget the account even when they liked the video.  
**Used for and where it works best:** Keep it to a single request, written and spoken at the same moment. In a series make it a pointer to the next part. If you are running a seamless loop, deliver the call in audio only so the visual loop is not broken. On a reel, write the request over the last live shot rather than cutting to a separate held frame, for the reason `promo.end_card` gives: a static frame at the end of a reel is dead air, and it costs completion.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Commercial / TVC, Product Video / Motion Design, Explainer, Corporate / Training, Vlog / YouTube Long-Form, Kids Content | genres: Science / Educational, Slice of Life, Family, Comedy, Drama  
**Avoid when:** Three requests at the end cancel each other and none of them happens. A long call to action eats the time that should serve the content. And where a performance ad closes on a person in frame, the request is theirs to say inside the same shot, as `promo.ugc_end_cta_offer` sets out, at that card's hold rather than this one's.  
**Prompt:** `final two seconds carry one short written request over the last live shot while it is still moving, centred in the safe band`  
`vertical.end_cta`

### List-Card Format

**Also called:** numbered cards, chapter cards  
**What it is:** Each item in the list gets a short card: a fixed number in the corner, a short title and a single shot that stands for it.  
**Effect on the audience:** It provides a clear structure the viewer can follow and mark their place in, and makes it easy to rewatch one specific item.  
**Used for and where it works best:** Ideal for facts, comparisons, tips and historical items. Keep the card design, position and typeface identical for every item. Give each item three to five seconds and save the strongest for last so viewers finish.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Explainer, Video Essay, Corporate / Training, Heritage / Historical Documentary, News Report / Reportage, Kids Content | genres: Science / Educational, Heritage (civilisation-focused), Historical / Biopic, Slice of Life, Family, True Crime, Nature / Wildlife  
**Avoid when:** More than five cards in a short video makes every one of them shallow. Cards whose images all look alike make the video feel stuck in place.  
**Prompt:** `numbered corner tag and a short title card for each item, one hero shot per item, identical layout throughout`  
**Yields to:** `vertical.countdown` — The items rank; count down instead.  
`vertical.list_cards`

### Countdown

**Also called:** reverse ranking, ticking clock  
**What it is:** The items run from weakest to strongest with the number falling: five, four, three, and the viewer waits for number one.  
**Effect on the audience:** It creates real anticipation because the best is reserved for the end, which lifts completion more than a plain list does.  
**Used for and where it works best:** Strong for rankings, comparisons and superlatives: the five oldest cities, the three strangest artefacts. Put the numeral large and always in the same corner. Give number one double the time and the best shot.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Video Essay, Explainer, Heritage / Historical Documentary, Documentary Series, News Report / Reportage, Kids Content | genres: Heritage (civilisation-focused), Historical / Biopic, Science / Educational, True Crime, Mystery / Whodunit, Nature / Wildlife, Sports Drama  
**Avoid when:** A long countdown in a short video makes viewers skip to the end. If number one is weak the whole video reads as a let-down and is remembered that way.  
**Prompt:** `large corner numeral counting down on every item card, the final item given twice the screen time and the best shot`  
**Yields to:** `vertical.list_cards` — No real ranking, or viewers skip ahead.  
`vertical.countdown`

### Watch-Till-The-End Tease

**Also called:** end tease, saved for last  
**What it is:** You announce early that the most important thing comes at the end, and remind the viewer once in the middle with an image or a short line.  
**Effect on the audience:** It gives an explicit reason to stay and lifts the completion rate, the strongest signal deciding whether a video travels.  
**Used for and where it works best:** Use it when you genuinely have a shot or a fact worth it: the rare piece, the final result, the biggest mistake. Show a glimpse of it, unclear, at the top. Make sure the ending delivers exactly what was promised.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Explainer, Video Essay, Heritage / Historical Documentary, Vlog / YouTube Long-Form, Kids Content, Commercial / TVC | genres: Science / Educational, Heritage (civilisation-focused), Historical / Biopic, Mystery / Whodunit, True Crime, Family, Comedy  
**Avoid when:** Promising a strong ending and delivering an ordinary one means the audience will not believe you next time. Do not repeat the reminder more than once or it becomes nagging.  
**Prompt:** `brief obscured glimpse of the final payoff in the opening, one short reminder mid video, full reveal in the last shot`  
**Yields to:** `vertical.result_first` — No payoff worth waiting for.  
`vertical.watch_till_end`

### Text Says What The Picture Cannot

**Also called:** complementary caption, information layer  
**What it is:** The burned text does not describe the image, it adds to it: the number, the date, the price, the name, or the opposing idea.  
**Effect on the audience:** It doubles the information in the same second, so the viewer receives two things at once and the video feels dense and worth the time.  
**Used for and where it works best:** In heritage documentary: the image carries the relief and the text carries the period and the place. On product: the image shows the use and the text gives the hard number. In comedy: the image gives the action and the text gives the contradicting thought, which is the core of the meme joke.  
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Meme / Comedy Edit, Heritage / Historical Documentary, Explainer, Product Video / Motion Design, Video Essay, News Report / Reportage, Lyric Video | genres: Heritage (civilisation-focused), Historical / Biopic, Comedy, Dark Comedy / Satire, Science / Educational, Slice of Life, True Crime  
**Avoid when:** Text repeating the image word for word wastes the most valuable space in the frame. Do not put a complex fact needing a long read over a fast shot.  
**Prompt:** `caption carrying the date and place layered over a macro shot of the detail, text adding information the image cannot show`  
**Yields to:** `vertical.captions` — The text must carry the spoken line.  
`vertical.text_beyond_picture`

### Action Falls in a Vertical Frame

**Also called:** the vertical axis, staging action for 9:16, descending action
**What it is:** The staging rule that follows from the shape of the frame. A 9:16 frame is tall and narrow, so **lateral movement crosses it in a fraction of a second and vertical movement stays in it** — a runner moving left to right is in and out before the eye reads them, while the same runner going down a stair, off a roof or into water occupies the whole frame for the whole move. The consequence is not a compositional preference, it is a staging instruction: **on a vertical piece, the action descends.**
**Effect on the audience:** Held, and without knowing why. A vertical chase staged laterally reads as a series of disconnected fragments because no shot can contain a whole movement; the same chase staged on the vertical axis reads as one continuous fall, and the viewer's sense of speed comes from the frame filling and emptying rather than from the cutting.
**Used for and where it works best:** Any vertical piece with movement in it — a chase, a fight, a fall, a pursuit, a collapse. **Design the route before the shot list**: give the sequence a vertical geography, so that the action has somewhere to descend through — a tower, a stair, a terraced mass, rooftops at several heights, a bank, water. A flat location kills a vertical action sequence, and the fix is the location, not the coverage. **Where the action must run laterally, put the camera on the axis instead** — run it head-on or directly away, so the movement becomes a change in scale within the tall frame rather than a traverse across a narrow one. **And stage the fight tight and low.** Two figures side by side do not fit; one above the other does, so a vertical fight is built on level changes — a fall, a pin on the ground, a grab from above — rather than on the lateral exchanges that horizontal fight geography assumes. `block.fight_geography` and `block.chase_geography` own the geography itself; this card is what the aspect does to it.
**Best in:** formats: Vertical Short-Form (Reels, Shorts, TikTok), Vertical Micro-Drama, Music Video, Commercial / TVC, Trailer and Teaser, Animated Series, Game Narrative | genres: Action, Thriller, Crime, Adventure, Horror, Fantasy and Epic
**Avoid when:** The piece has no movement to stage — an interview, a talking head, a static explainer, a piece built from stills. It also does not apply to a horizontal master being reframed to vertical, where the action was staged for another shape and the job is `control.aspect_reframe` rather than restaging.
**Yields to:** `vertical.safe_zones` — a descending move that carries the subject through the reserved top or bottom band has been staged into the interface, and the band wins.
**Prompt:** `staged on the vertical axis: the action descends through the frame, camera at the level of the movement, the subject filling the tall frame from top to bottom`
`vertical.action_descends`
