Matte compositing

Matte compositing is a visual effects technique used to combine multiple images or video layers into a single seamless scene. It involves creating a "mask" (the matte) that specifies which parts of the foreground image are visible and which parts are transparent. This allows filmmakers to replace or insert backgrounds, add digital effects, or combine live-action footage with computer-generated elements. The process relies on precise control of transparency and matching lighting to make the composites look natural. Essentially, matte compositing is a way to digitally blend different visual components to craft a cohesive final image.
