Seedance 2.5

Seedance 2.5 is ByteDance’s follow-up to Seedance 2.0, built to create native 4K video clips up to 30 seconds without manual splicing. It accepts up to 50 multimodal references — text, images, audio and 3D files — to keep characters, lighting and style consistent across a piece and reduce visual drift.

The tool offers partial editing so you can change specific target areas without re-rendering the whole video, and it includes a 3D white-model preview aimed at industrial spatial simulation. Everything runs in the browser, so you don’t need a local GPU to generate content.

• 30-second native 4K output
