FAQ
About SeeDance 1.0 Fast API
You build one to six segments. Each segment has its own prompt, optional image, and duration chosen from the allowed per-segment lengths.
Controls match Mini in the playground. Fast maps to the Fast pricing and latency profile; Mini maps to the Mini SKU.
The client sends 720p for multi-frame jobs while other modes honor your 720p or 1080p selection.
