Keying is an essential technique in compositing that allows you to remove a subject from its background and place it into a new environment seamlessly. It saves time and effort compared to manual rotoscoping, which is the task of cutting out frame-by-frame. Keying delivers a more realistic result, preserving fine details such as hair, fur and more.
