概要

このモデルについて

Seedance 2.5 Motion Control is the Seedance 2.5 version of Motion Control: it recasts an existing performance video with new performers while automatically preserving the source clip's motion, choreography, blocking, and camera work, and while keeping the original location intact. Upload a reference video plus character reference image(s) of the new performer(s) and an optional short instruction — the model extracts the motion/camera geometry and a clean background plate from your reference video, builds a multi-angle identity sheet from each character photo, and hands everything to Seedance 2.5 Omni Reference (720p) to render the recast.

1Dance/choreography recast: Swap the performer(s) in a dance or movement clip with a different character while keeping the exact choreography and camera work.
2Brand/UGC recreation: Recreate an existing ad or social clip's blocking and camera moves with your own talent or product.
3Location-preserving swaps: Replace the people in a video while keeping the real filming location, lighting, and architecture intact.
4Multi-character recasts: Replace two or more performers at once, each mapped to its own character reference photo, with up to 30 reference images supported.

muapiappBase 720p Omni Reference rate + preprocessing (depth + environment + per-character sheets)

Single billed request covers the full pipeline: depth extraction, environment clean-plate generation, character-sheet generation, and the final recast render.

Fal.ai利用不可

No equivalent single-request motion-recast pipeline is offered — achieving the same result would require manually chaining several separate models.

プロンプトstring

Optional short creative brief describing the recast, e.g. 'swap the two dancers with the people in the reference images'. If omitted, roles are inferred automatically from the reference video and images.

参照動画string

Reference video whose motion, choreography, blocking, and camera work will be preserved. The original performers and location are automatically replaced.

実装ガイド

開発者ドキュメント

  1. Upload the reference video (video_url) whose motion, choreography, blocking, and camera work should be preserved.
  2. Upload one character reference photo per performer you want to recast (images_list, up to 30) — each gets its own multi-angle identity sheet generated automatically before the final render.
  3. Optionally add a short prompt describing the recast; if omitted, roles are inferred automatically from the video and images.
  4. Set aspect_ratio, duration (4-30s), seed, and high_bitrate if needed.
  5. generate_audio is off by default — the recast has no synthesized music/SFX unless explicitly enabled.
  6. Poll or use webhook to retrieve the completed video.

よくある質問

FAQ

What exactly gets preserved from the reference video?

Motion, choreography, blocking, timing, and camera work (angle, framing, movement) are preserved. The original performers' identity, wardrobe, and colors are replaced, while the real filming location, architecture, and lighting are kept intact.

Can I recast more than one performer?

Yes — provide one character reference photo per performer in `images_list` (up to 30). Each photo gets its own automatically generated multi-angle identity sheet, so multiple performers can be swapped in a single request.

Does the output include generated audio?

No, not by default. `generate_audio` defaults to false, since a motion-control recast is meant to preserve an existing performance rather than add fabricated music or sound effects. Set it to true to opt in.

How is this different from Seedance 2 Motion Control?

Same recast pipeline (depth extraction, environment clean-plate, character sheets, structured prompt generation), built on Seedance 2.5 Omni Reference instead of 2.0 — supports up to 30 reference images (vs. 9), longer durations (up to 30s vs. 15s), and adds `seed`/`high_bitrate` controls.

How is cost calculated?

Base generation cost is the same as Seedance 2.5 Omni Reference (720p rate x output duration, with a discounted combined rate when a reference video is used), plus internal preprocessing: depth extraction ($0.04/sec of the source video), an environment clean-plate pass (2 frames, $0.06 each), and one character-sheet generation per reference photo ($0.09 each).
