Seedance 2.0 Video-Edit
Seedance 2.0 Video-Edit transforms an input video from a natural-language prompt — change lighting, weather, style, environment, or specific elements while preserving the subject identity, composition, and motion of the original. Built on ByteDance Seed's unified multimodal architecture for cinematic, motion-stable output.
Key Features
- Conversational video editing — Describe the change in plain language; the model rewrites the scene while keeping the original motion intact.
- Subject and motion preservation — Faces, objects, and camera movement from the input video stay consistent through the edit.
- Multi-reference support — Optionally guide style, character identity, or audio with reference images and audio clips.
- Native audio synchronization — Generates synchronized audio in a single pass.
- Cinematic output quality — Director-level lighting, framing, and motion stability inherited from Seedance 2.0.
