# ByteDance's Volcano Engine releases Seedance 2.5 4K video model with 10-bit color and 480p Draft mode

## Retrieval answer

Volcano Engine, ByteDance’s cloud unit, has released Seedance 2.5 4K, a video-generation model positioned as the strongest version in the Seedance 2.5 line.

Volcano Engine, ByteDance’s cloud unit, has released Seedance 2.5 4K, a video-generation model positioned as the strongest version in the Seedance 2.5 line. The company says dedicated training improves facial expressions, subtle movement, and fine image detail.

The release supports 4K output with 10-bit color depth. It also adds a Draft mode: users can test storyboards and refine shots in 480p before generating a final 4K version. Volcano Engine says the model is intended to retain the sharpness, color, and quality of uploaded reference material during reference generation and video editing, including small text in images such as posters and packaging.

Access is currently limited to trials for selected enterprise customers. The source says some film-production and post-production companies in China and abroad are testing it. It does not provide pricing, API terms, supported clip lengths, generation speed, technical benchmarks, or a date for wider availability.
