Remove Video Backgrounds in ComfyUI Transparent Output Workflow Tutorial

Описание: Learn how to remove the background from video using ComfyUI with a simple streamlined workflow.

In this tutorial I walk through how to load a video, use BiRefNet segmentation to remove the background frame-by-frame, and export a transparent video with an alpha channel.

This workflow is great for creating:
• transparent video assets
• green-screen style footage
• compositing subjects into other scenes
• AI video editing workflows
