Seedance 2 Motion Control: AI 视频编辑器

为现有表演视频替换表演者，同时保留原有动作、编舞、镜头调度和场景。免费试用，按次生成付费，无需订阅。 Seedance 2 Motion Control 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 Omni Reference to render the recast.

关于此模型

Seedance 2 Motion Control 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 Omni Reference 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.

成本分析

muapiapp~$2.46 for a 5s recast (5s reference video, 1 character photo, high quality)

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

Fal.ai暂不可用

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

Replicate暂不可用

No equivalent single-request motion-recast pipeline 是offered on Replicate.

配置参数

提示词string

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

默认值Swap the two dancers with the people in the reference images, keep the same room.
参考视频string

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

默认值https://d3adwkbyhxyrtq.cloudfront.net/webassets/videomodels/seedance-v2.0-omni-reference.mp4
Character 参考图像sarray

Character 参考图像 — the new performers who will be recast into the video, in the order they should appear.

默认值https://cdn.muapi.ai/assets/image_download_21.avif
画面比例枚举（6 个选项）

输出视频的画面比例。

默认值16:9
质量枚举（2 个选项）

Generation quality. 'high' uses the standard model, 'basic' uses the faster model.

默认值high
时长（秒）int

Video duration （秒） (4-15).

默认值5
生成音频boolean

Generate audio (music/SFX) for the recast video. Off by default — a motion-control recast usually shouldn't have fabricated audio layered over the preserved performance.

默认值false

实施指南

开发者文档

  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 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. 将 aspect_ratio, quality (high or basic), and duration (4-15s).
  5. generate_audio 是off by default — the recast has no synthesized music/SFX unless explicitly enabled.
  6. Poll or use webhook to retrieve the completed video.

常见问题

常见问答

参考视频中具体会保留哪些内容？

动作、编舞、走位、时序和镜头调度（角度、构图、运动）都会保留。 原表演者的身份、服装和颜色会被替换，同时保留实际拍摄地点、建筑和灯光。

可以替换多位表演者吗？

Yes — provide one character reference photo per performer in `images_list` (up to 9). 每个photo gets its own automatically generated multi-angle identity sheet, so multiple performers can be swapped in a single request.

输出是否包含生成的音频？

默认不会。 `generate_audio` defaults to false, since a motion-control recast 是meant to preserve an existing performance rather than add fabricated music or sound effects. 将 it to true to opt in.

我需要编写详细提示词吗？

不需要，`prompt` 是optional. If omitted, the character and environment roles are inferred automatically by analyzing the reference video and the character images you provide.

如何计算费用？

Base generation cost 是the same as Seedance 2 Omni Reference (rate x 输出duration, plus a discounted rate for the reference video's own duration), 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). Example: 5s output, 5s reference video, 1 character photo, 'high' quality ≈ $2.46 total.

支持哪些宽高比和分辨率？

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