# BriaTransparentVideoBackground - ComfyUI Built-in Node Documentation

> This node removes the background from a video using Bria's AI service and outputs the cut-out frames along with an alpha mask.

This node removes the background from a video using Bria's AI service and outputs the cut-out frames along with an alpha mask. Connect both outputs to a compositing node, or feed them to a Save WEBM node to write a transparent video.
