Seedance 2.0 Reference to Video
Seedance 2.0 Reference to Video is a standard route that uses reference images, video, or audio to guide subjects, motion, visual style, and sound. Media URLs are submitted to asset review before task creation by default (real_person=true); set real_person=false only when the materials are confirmed face-free.
Asset and Scene Limits
Seedance 2.0 reference-material mode supports 9 reference images, 3 reference videos, and 3 audio clips. It is a full-capability route that supports real-person content and faces; materials are submitted to asset review by default (real_person=true), and setting real_person=false passes materials through without review when they are confirmed face-free.- Text prompt: For Chinese, keep it under 500 characters; for English, under 1,000 words.
- Image input: Supports jpeg, png, webp, bmp, tiff, gif, heic, and heif; each image under 30 MB; aspect ratio (0.4, 2.5); width and height (300px, 6000px).
- Multimodal reference scenes: No more than 9 images.
- Video input: Supports mp4 and mov; each video 2–15 seconds; up to 3 reference videos; total video duration must not exceed 15 seconds; each video under 50 MB; frame rate [24, 60].
- Audio input: Supports wav and mp3; each clip 2–15 seconds; up to 3 reference audio clips; total audio duration must not exceed 15 seconds; each clip under 15 MB.
- Audio input restriction: Audio cannot be provided on its own; at least one reference image or video is required.
Real-person review (real_person)
When a request carries reference materials, the booleanreal_person field controls whether materials are submitted to face review first:
real_person: true(default): materials are submitted to the asset review service first, and the task is created withassetId://{assetId}references; the task waits during review and fails if review rejects the materials.real_person: false: review is skipped and material URLs are passed through to task creation as-is.
false only when the materials are confirmed face-free to save the review round trip; keep the default true for materials containing real people.
Asset library references
Besides publicly accessible URLs, theimage_url / image_urls, video_urls, and audio_url / audio_urls fields also accept asset library references in the form assetId://{assetId}. Asset IDs are shared across the platform: any account may reference a known assetId, regardless of who submitted it — the same sharing semantics as a public URL. Only ACTIVE assets pass validation. Submit and track assets via asset upload and asset detail.Authorizations

Lengthy text will lead to scattered information, and the model may ignore details and only focus on key points, resulting in missing elements in the generated video.

This can improve the timeliness of generated videos but will also introduce a certain degree of latency.
Controls whether the generated video contains audio synchronized with the visuals.
Whether to return the last frame image of the generated video. Using this parameter enables the generation of multiple consecutive videos: taking the last frame of the previous generated video as the first frame of the next video task to quickly generate multiple consecutive videos, and the first item in the returned result is this image.
Whether the reference materials contain real people (human faces). Defaults to true: materials are submitted to the asset review service and replaced with assetId:// references before task creation. Set to false only when the materials are confirmed face-free to skip review and pass material URLs through as-is.
