# Media Inputs, Edits And Reuse

Use PixVerse's offline Create contracts and the wrapper's actual supported parameters
for image/video/audio generation. Use FFmpeg/ffprobe for local media inspection,
extraction and editing. Read only the input family needed by the current request.

## Media Roles And Job Lifecycle

Keep local file, provider media path, upload ID and generation job ID distinct.
Use documented role mappings, ordered image/video/audio arrays and current limits.
An endpoint image is not a general style reference. Audio input does not imply an
output-audio toggle. Reuse accepted assets through provider paths and receipts;
record parameters actually returned. Recover uncertain submissions by ID.

## Image And Video Edits

- Image edits and refinements use Sunburst 2K/high. Bind the accepted image, state the
  specific change and protect its identity, composition, aspect and unchanged text.
- Localized video edits need the actual source video, the requested change and any
  reference frame's exact source time. Use only roles supported by the selected video
  mode. A still-image edit alone does not change the corresponding video frames.
- Crop, contain-fit, letterboxing, trims and graphic overlays use FFmpeg. Preserve
  chronology and accepted audio. Outpainting requires a supported generative mode;
  a crop does not reveal unseen pixels.
- Continue or modify motion using the actual source video and supported edit/extend
  mode. Keep source timing, reference authority and the intended start/end state.
- For character continuity, use accepted images and the separate identity, expression,
  wardrobe and scene roles in `../skills/pixverse-character-sheet/references/identity.md`.

## Reusable Creative Inputs

Store the accepted creator, product, brand, hook, setting and ad reference in local
project memory. Record exact spelling, real product/packaging images, dimensions,
visible features, supplied claims and source files. Keep a hook distinct from a style
image or product reference. Reuse a canonical product/brand record across outputs.

Select the concrete workflow by the requested result: creator UGC, product showcase,
try-on, unboxing, tutorial or cinematic ad. Reference-led work uses reference information
already obtained by Codex or supplied by the user; Codex chooses how to acquire and
understand the source. A fresh concept starts from its chosen hook and setting.
Keep observed reference details distinct from creative assumptions.

## Sound

Use voiceover for exact spoken copy, music generation for a requested soundtrack,
and video-native sound for visible synchronized events. Existing sound effects can
be extracted, trimmed or mixed with FFmpeg. Use a standalone generation mode only
when the current CLI contract exposes that media type; preserve the actual output
role rather than calling a music bed an isolated sound effect.

Specialized multi-shot prompts retain all shot, voice and reference instructions.
Shared descriptions can be concise; prompt budgets do not remove required events.
