Generate video with SeeDance 2.0 Mini
ByteDance SeeDance 2.0 Mini — the same modes as SeeDance 2.0 (text / image / reference / video-to-video) at the best cost-performance. Resolutions 480p and 720p (see resolution_pricing in GET /v1/models). Optional audio.
Asynchronous. Returns a job id (the video is not in this response). Poll GET /v1/videos/{id} until status is succeeded — the video URL is in that response’s video_url.
