What Seedance 2.5 is good for
Seedance 2.5 is ByteDance's newer video model, built for longer scenes than Seedance 2.0, with native 1080p output. It reads a large mix of reference images, clips, and audio to keep characters, products, and brand assets steady, and it can edit existing footage while leaving key elements intact. It suits ad teams, product marketers, and storytellers who need control over every shot.
- Longer story scenes with several beats and sound
- Product ads that open on your own product photo
- Scenes where you direct both the character's performance and the camera
- Polished 1080p clips for ads, trailers and brand stories

What is new in Seedance 2.5 compared with Seedance 2.0?
Seedance 2.5 makes longer clips and gives tighter control when many references are mixed, from images and video to audio and text. It adds planning tools such as 3D white-model previews of layout, camera paths, and motion before the final render, and handles edits to existing footage more reliably.
Can Seedance 2.5 use a first frame, a last frame, and references in one request?
No. Starting from a first frame, moving between a first and a last frame, and working from mixed references are three separate modes, and a last frame only works together with a first frame. When the clip must open and close on exact images, pick first and last frames instead of references.
