## Request body

- Seedance25MotionControlRequest
  - `webhook_url` string, uri, nullable
  - `duration` integer: Video duration in seconds, from 4 to 30.
  - `aspect_ratio` 'adaptive' | '16:9' | '9:16' | '1:1' | '4:3' | '3:4' | '21:9' | '9:21'
  - `seed` integer, nullable: Random seed for reproducible generation. Use -1 for random.
  - `high_bitrate` boolean
  - `prompt` string, nullable: Optional short creative brief describing the recast, e.g. 'swap the two dancers with the people in the reference images, keep the same room'. If omitted, the identities/roles are inferred automatically from the reference video and images.
  - `video_url` string, uri, required: Reference video whose motion, choreography, blocking, and camera work will be preserved.
  - `images_list` string[], nullable: Up to 30 character/location/style reference images used to recast the performers and environment.
  - `generate_audio` 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.
