Seedance 2.0 Fast - Reference to Video

Try Seedance 2.0 Fast - Reference to Video in the Workbench

Run this model interactively, tune parameters, and compare outputs.

Model ID: bytedance-seedance-2-0-fast-reference-to-video ByteDance Seedance 2.0 Fast generates video from a text prompt guided by reference images, videos, and audio. Reference media are addressed in the prompt as [Image 1], [Video 1], [Audio 1] (1-based positional index within each media type).

Example request

Use the Workbench as a request builder: configure parameters for this model in the UI, then open the API tab to copy the exact cURL or Python call.

Sync
Async
Async with SSE

This blocks until the video is ready (typically 5-15 minutes). Prefer Async or Async with SSE for anything beyond quick experimentation.See the video generation reference for more details.

Request parameters

Required parameters

Field	Type	Default	Description
`prompt`	`string`	—	The text prompt used to generate the video. Use [Image 1], [Video 1], [Audio 1], etc. (1-based positional index within each media type) to reference inputs. Face-containing media is indexed before non-face media within its type.

Optional parameters

Field	Type	Default	Description
`input_face_images`	`array<string>`	—	Place reference images here when they show a real human face. Content filters may block the request otherwise.
`input_images`	`array<string>`	—	Reference images that guide the generated video. Up to 9 total reference images and up to 15 total references across all types may be used.
`input_face_videos`	`array<string>`	—	Place reference videos here when they show a real human face. Content filters may block the request otherwise.
`input_videos`	`array<string>`	—	Reference videos that guide the generated video. Up to 3 total reference videos and up to 15 total references across all types may be used.
`input_audios`	`array<string>`	—	Reference audios that guide the generated video. Up to 3 total reference audios and up to 15 total references across all types may be used.
`resolution`	`string`	`"720p"`	Video resolution. One of: 480p, 720p.
`duration`	`integer`	`-1`	Duration of the video in seconds. Supports 4 to 15 seconds, or auto to let the model decide based on the prompt. One of: -1, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15.
`aspect_ratio`	`string`	`"adaptive"`	The aspect ratio of the generated video. Use 16:9 for landscape, 9:16 for portrait/vertical, 1:1 for square, 21:9 for ultrawide cinematic, or auto to let the model decide. One of: adaptive, 21:9, 16:9, 4:3, 1:1, 3:4, 9:16.
`generate_audio`	`boolean`	`false`	Whether to generate synchronized audio.
`watermark`	`boolean`	`false`	Whether to add an ‘AI generated’ watermark to the output.
