Finalement

Compositing in VFX (Visual Effects) is the process of combining multiple visual elements (images, videos, CGI, special effects) to create a final, cohesive, and realistic scene. This involves merging different layers of images from various sources, such as live-action footage, computer-generated elements (CGI), digital special effects (e.g., explosions, fire, etc.), or green screen backgrounds, to give the illusion of a single, coherent scene.
