Seedance 2.5
A 30-second video generation tool with reference files and native audio
About Seedance 2.5
Seedance 2.5 is a video generation model announced by ByteDance at the FORCE conference in June 2026. It can render a continuous video of up to 30 seconds in one generation, accept up to 50 image, video, and audio reference files, and generate native audio in more than 10 languages. The platform offers region-level editing: users can select a label, face, or background and describe the desired correction; the official page says that timing, composition, and audio in the remaining clips stay unchanged.
