Seedance 2.5

Seedance 2.5 is ByteDance's next-generation AI video generator built for longer, more controlled video creation. You describe a shot or provide reference images, and it produces continuous 30-second 4K videos in a single take—no stitching, no re-cuts needed. The model handles multimodal inputs: text prompts, up to 9 images, 3 video references, and 3 audio files at once, letting you lock in characters, style, and motion across the whole clip.

What makes it different from the previous version is the native 4K output, stronger continuity over longer sequences, and local editing—you can adjust one region of the video without regenerating the entire thing. That matters for real work: approve one ad spot, then swap a product or region for different markets without reshooting.

It's built for filmmakers, agencies, product teams, and content creators who need production-ready video faster. Text to video, image to video, or a mix—choose your aspect ratio (16:9, 9:16, 1:1), resolution up to 4K, and length up to 30 seconds. The tool runs in your browser, no install needed.
