This workflow is designed for effortlessly replacing characters in videos. All you need to provide are two things: a video showing the desired movements, and an image of the character you want to use. Replacement Mode: Swap the main person in the original video with your new character, while seamlessly keeping the original background and movements intact. Unlike the complicated official setup, this simplified version hides all the technical clutter. You don’t need to worry about video length or tedious settings—everything is automated so you can get high-quality, stable, and smooth videos with just one click.
