Seedance 2.5 US
Seedance 2.5 US is the US-hosted edition of ByteDance's Seedance 2.5. It generates clips from 4 to 30 seconds at 480p, 720p, or 1080p with native synchronized audio, from text, from first and last frames, or from up to 30 reference images, 10 video clips, and 10 audio files. To restyle a whole clip shot for shot, pass a restyled still of its first frame as `first_frame` and the source clip as `reference_video`. Use it when the generation must run on US infrastructure.
