Use with the Workers AI binding, the AI Gateway REST API, or the Unified API.

Bria's video background removal replaces the background of a clip up to 60 seconds long with a solid color or with transparency. Transparent output needs the mov_proresks (ProRes) preset. Frame rate and audio are preserved, and the output resolution matches the input unless auto_zoom crops to the subject.
