What does the term "compositing" refer to in VFX?

The term "compositing" in the context of visual effects (VFX) specifically refers to the process of overlaying multiple visual elements into a single image. This technique combines various layers, which can include live-action footage, digital elements, and background imagery, to create a cohesive final piece. Compositing is fundamental in filmmaking and VFX as it allows filmmakers to blend real and digital worlds seamlessly, enabling the creation of complex scenes that would be impossible or impractical to achieve in a single take.

This process often involves techniques such as keying (removing backgrounds, such as in green screen applications), layering, and blending different visual elements together to achieve the desired effect. The end goal of compositing is to integrate these elements in a way that appears natural and visually consistent within the context of the scene, enhancing the storytelling and visual impact of the film.
