概要

このモデルについて

更新日: 2026年11月9日

Seedance 2 Spicy Motion Control recasts the performers in an existing performance, dance, or UGC video with a bolder creative treatment while preserving the original motion, choreography, blocking, camera work, timing, and location. Provide a source video plus up to 9 character reference images and an optional instruction. Muapi automatically extracts motion and camera geometry, cleans representative environment frames, builds a multi-angle identity sheet per character, and renders the final recast through the Spicy Seedance 2 path. The request shape matches the standard Seedance 2 Motion Control endpoint, while this variant selects the relaxed-moderation model family and carries a 10% tier surcharge.

1Bold music-video recasts: replace performers in a choreography clip while keeping the original movement and camera language.
2High-impact social edits: produce punchier performer swaps for UGC, fashion, nightlife, or event campaigns.
3Stylized character replacement: preserve a real location and performance while introducing a more dramatic visual direction.
4Multi-performer concepts: use up to 9 character references to recast a group without rebuilding the source scene.

How to Use Seedance 2 Spicy Motion Control

  1. Provide a publicly reachable 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 9) — 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. Describe the desired bold treatment in prompt if needed. Set aspect_ratio, quality (high or basic), and duration (4-15s).
  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 9). 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.

Do I need to write a detailed prompt?

No — `prompt` is optional. If omitted, the character and environment roles are inferred automatically by analyzing the reference video and the character images you provide.

How is cost calculated?

The price is the standard Seedance 2 Motion Control price multiplied by 1.1 (a 10% spicy-tier surcharge). That standard price covers the Omni Reference render plus internal preprocessing: depth extraction (duration-based), an environment clean-plate pass, and one character-sheet generation per reference photo.

What aspect ratios and resolutions are supported?

21:9, 16:9, 4:3, 1:1, 3:4, and 9:16 aspect ratios; output renders at 720p.

How does the Spicy variant differ from standard Seedance 2 Motion Control?

Inputs and outputs are identical. The Spicy variant renders through the relaxed-moderation model family, which suits bolder creative treatments, and is priced 10% above the standard endpoint.
