Doubao Seedance 2.5 is ByteDance's next-generation video generation model, designed to evolve from a creative tool into a productivity powerhouse. Its key breakthrough is the ability to generate native 30-second single-segment videos in one go, eliminating the need for post-production stitching. The model supports the joint generation of up to 50 multimodal assets (images, videos, audio, etc.) and introduces local video editing for precise modifications. It natively supports over 10 languages and allows timestamp-based control over video content.
