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 Fast reference-to-video generates video from a text prompt guided by reference images, videos, and/or audio. This is the enterprise fast tier with lower latency and cost. Reference media are addressed in the prompt as @Image1, @Image2, @Video1, @Video2, @Audio1, etc.

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 @Image1, @Video1, @Audio1, etc. to refer to reference media.

Optional parameters

Field	Type	Default	Description
`input_images`	`array<string>`	—	Reference images to guide video generation. Refer to them in the prompt as @Image1, @Image2, etc. Supported formats: JPEG, PNG, WebP. Max 30 MB per image. Up to 9 images. Total files across all modalities must not exceed 12.
`input_videos`	`array<string>`	—	Reference videos to guide video generation. Refer to them in the prompt as @Video1, @Video2, etc. Supported formats: MP4, MOV. Up to 3 videos, combined duration must be between 2 and 15 seconds, total size under 50 MB. Each video must be between ~480p (640x640) and ~720p (834x1112) in resolution.
`input_audios`	`array<string>`	—	Reference audio to guide video generation. Refer to them in the prompt as @Audio1, @Audio2, etc. Supported formats: MP3, WAV. Up to 3 files, combined duration must not exceed 15 seconds. Max 15 MB per file. If audio is provided, at least one reference image or video is required.
`resolution`	`string`	`"720p"`	Video resolution - 480p for faster generation, 720p for better quality. One of: 480p, 720p.
`duration`	`string`	`"auto"`	Duration of the video in seconds. Supports 4 to 15 seconds, or auto to let the model decide based on the prompt. One of: auto, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15.
`generate_audio`	`boolean`	`true`	Whether to generate synchronized audio for the video, including sound effects, ambient sounds, and lip-synced speech. The cost of video generation is the same regardless of whether audio is generated or not.
`aspect_ratio`	`string`	`"auto"`	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: auto, 21:9, 16:9, 4:3, 1:1, 3:4, 9:16.
`seed`	`integer`	—	Random seed for reproducibility. Note that results may still vary slightly even with the same seed.
