Seedance 2.5 from ByteDance is now available on AI Gateway. It can generate up to 30-second clips with synchronized audio, and takes up to 50 reference inputs in one request, spanning images, video, audio, and style.

A single clip holds camera movement and continuity without stitching shots together in post, and short clips can be extended, carrying over character, scene, and camera movement. Prompts work in more than ten languages.

Seedance 2.5 can also edit a finished video in place, swapping backgrounds, products, or characters while the frame, camera, and pacing stay fixed, so one shoot yields several variants.
