Seedance 2.5
Seedance 2.5 generates audio and video together. It can produce up to 30 seconds in one pass and continue a video across further requests.
Technical guide
The API distinguishes reference generation, editing and extension. For editing, it requires an adaptive aspect ratio and duration of -1 so the source clip controls both. Timestamp-based edits can target a particular part of a clip.Seedance 2.5 API tutorial
Practical use
Practical guidance. Use separate reference assets for appearance, motion and sound. For an edit, identify the target clip and time range explicitly. Review the entire output for unintended changes beyond that range.
