Body
Use volc-asset-video. For specific content requests, select volc-asset-video-nsfw under the Direct resource group.
volc-asset-video, volc-asset-video-nsfw "volc-asset-video"
Asset group ID.
"group-20260319072926-rrnmg"
Asset type. Fixed value Video. Supported formats: MP4 and MOV. Resolution: 480p, 720p, 1080p, or 4K. Duration: 2–30 seconds. Aspect ratio: 0.4–2.5. Width and height: 300–6000 px. Total pixels: 407696–2086876. File size: no more than 200 MB. Frame rate: 24–60 FPS. All constraints apply together.
Video "Video"
Publicly accessible video URL. Base64 video input is not supported. The referenced file must satisfy the Video limits listed under AssetType.
"https://example.com/video.mp4"
Asset name, up to 64 characters. Used only for fuzzy search in ListAssets and not passed to model inference.
64"scene-clip"
Project that owns the asset. Must match the ProjectName of the target asset group; omit it for the default project.
"default"
Response
The video was accepted for asynchronous processing. Poll GetAsset until Status becomes Active or Failed; upload-time SLA is not guaranteed. Video activation is typically 9–12 seconds in ideal conditions and may take about 10 seconds to 2 minutes when the review queue is congested.
Asset ID. After Status becomes Active, use asset://<ID> in Seedance requests instead of the temporary GetAsset URL.
