A transition marks a change of place, topic or kind of shot, and the good ones are caused by something on screen.\n\nThis skill needs the Tella MCP. If tools such as `get_timeline` are missing, follow the connection steps in the `tella` skill first.\n\n## What Tella has\n\n- Between clips: `transition` on `update_clip` (`smooth` or `hard_cut`), or `defaultClipTransition` on `update_video` for every clip.\n- Between layouts: `transitionStyle` on a timed layout (`spring` or `hardCut`), at the pace of `layoutAnimationStyle` on `update_video` (`gentlest` to `snappiest`).\n- Zooms: `introTransition` and `outroTransition`, at the pace of `zoomAnimationStyle`. Overlays and text: their `animation`.\n- Tella Motion: `setTransition` between items of a sequence (`crossfade`, `left`, `right`, `up`, `down`), and anything you build with keys, masks (`setMasks`), blur and mattes.\n\n## Which one\n\n- Same speaker, same place: a hard cut, or a punch-in (`tella-camera-moves`).\n- Screen and camera changing shape: `spring` layouts at one pace for the whole video.\n- A new topic, place or b-roll world: a built transition, inside the Tella Motion shot or as a short Tella Motion b-roll (`add_layout` with `media: {type: \"motion\", documentId}`):\n  - **zoom through**: push into an element (a button, a card, a word) until its colour fills the frame, and start the next shot from that colour;\n  - **grow into**: a card grows past the frame edges and becomes the next shot;\n  - **wipe or iris**: a keyed mask opens from where the action was, such as the click;\n  - **match cut**: the same shape or word in the same place on both sides;\n  - **whip**: a fast blurred move, the next shot arriving the same way at the same speed;\n  - **colour flood**: the subject stays while the ground changes colour.\n- Three to five kinds in a video at most. No crossfade between two different worlds, and no transition on every cut.\n\n## Timing\n\nMoves take 0.3 to 0.6 s and hand off as `tella-motion-design` says (Between shots). A transition never hides a word: put it in a pause or under the first word of the new thought.\n\n## Check\n\n`get_filmstrip` at -0.2, -0.1, 0, +0.1 and +0.2 s around every transition: no white, black or empty frame, no jump, nothing half-built.\n"
