Remove Video Background for iMovie

iMovie is Apple's free video editor for Mac, iPhone, and iPad. It has a green/blue screen effect for chroma keying, but it cannot remove arbitrary video backgrounds. RemoveBackgroundAI lets you remove any video background with AI, then import the result as an overlay in iMovie for professional-looking composites without a physical green screen.
