Segment Anything 2 - Replace video BG with SD image workflow

In this workflow, I'll guide you through the process of using Segment Anything 2 to remove the background of a video and replace it with an AI-generated image. We'll start by importing our video into the Segment Anything 2 interface. Next, I'll show you how to use the segmentation tools to accurately select and remove the background. Once the background is removed, we'll dive into generating a new background image using Stable Diffusion.

This workflow is perfect for anyone looking to enhance their video editing skills with the power of AI, but particularly those interested in masking or controlling specific aspects of a video.

Example uses SD 1.5, but can be slightly changed for any base model, or take it a step further and use a post-editing tool to use any still image.
