# Seedance 2.5 Skill

## Language route

- For an English request, follow this file and the `*.md` references.
- For a Chinese request, read [the Chinese workflow](references/workflow.zh-CN.md)
  first, then use the matching `*.zh-CN.md` reference files.
- Keep model IDs, JSON keys, commands, media placeholders, and native-audio
  symbols exactly as code. Do not translate them.

Do not force every request through one image-grid pipeline. Choose the video
route first, then enable only the preparation modules the job needs.

## 1. Choose the creative route

| Need | Route | Inputs | Result |
|---|---|---|---|
| One short, simple scene | T2V | Text prompt | One self-contained shot |
| A multi-shot sequence with readable panels | R2V storyboard | One complete storyboard image | One request turns panel order into a continuous video |
| A clip controlled by people, product, scene, or style assets | R2V asset references | A small role-specific asset pack | One clip built from those references |
| A shot with an exact beginning and ending | I2V shot pair | Start and end keyframes | One independently reviewable shot |
| An uninterrupted action exceeding the supported duration | Extend / chain | Previous generated tail frame and next prompt | Continuation of the same shot |
| One continuous piece carrying several events | Staged whole-short | Text plus optional references | One request covering ordered stages, each landing on a stated end state |
| A scoped change to an existing video | Editing | Source video plus target references | The source with only the named region or element changed |
| A bridge between two finished clips | Seamless transition | Two videos | Generated bridge content between them |
| Motion, blocking, and camera taken from a 3D preview | Blockout reference | Coarse or fine blockout video plus look references | Final render following the blockout's timing and staging |

Use Seedance 2.0 as the executable default. Offer a Seedance 2.5 whole-short
route only when the selected provider exposes that model and its actual limits.

The last four routes depend on capabilities that differ per model and per
provider. Verify availability before offering one; see
[capabilities](references/capabilities.md) for the 2.0/2.5 comparison and for
which published capabilities are platform features rather than API parameters.

### Storyboard or individual keyframes

- Use the **whole storyboard image in one R2V request** by default whenever
  individual panels remain visually readable. Do not crop it first. Seedance
  can interpret the ordered panels as one continuous multi-shot video.
