Compositing in animation is similar to compositing in still image editing but with motion. Compositing is the combining of two or more images still or motion into a single image or shot. There are multiple ways to achieve this from a green screen to various software. We are going to start with a simple animation added to a photo background to create a composite video shot. There are four key elements to pay attention to in order to get a believable composite: camera angle, lighting, shadows, and interaction.
