Also known as: Compositing artist, Finishing artist
What does a compositor do?
Compositors create the final image of a frame, shot or sequence. They take different digital elements; like the animations, background plates, graphics and special effects (SFX) and put them together to make a believable picture.
They are responsible for the composition of images and shots. They make these look good by way of how the different art assets and elements are digitally placed. Compositors enhance the lighting, create convincing shadows and add motion blur where required.
They are also responsible for continuity; making sure art from different sources and different artists looks the same. They make sure the blacks and other colours match each other in the image. They spot mistakes and either correct them or send the work back through the pipeline to be improved. They ensure the overall style of the film is consistent and in line with the director’s vision.
Some studios have junior compositor roles. Junior compositors help compositors by doing the simpler parts of the job, sometimes under supervision. They might match colours or add in shadows.

Who does a compositor work with?
Compositors work with the artists that create all the different elements (also known as ‘art assets’ of an animation). They work most closely with the lighting artists, as lighting is such an important part of an animated film. They also communicate with the director as they are working to the director’s vision.
How do I become a compositor?
It takes many years working in the animation industry to become a compositor. However, some companies have junior compositor roles, which give you the opportunity to develop into a senior compositor position. You might get into a junior compositor role straight after college or university or you might start in a related role, such as a roto artist or modeller, and work your way into the compositor role from there.

An apprenticeship is a job with training, so it’s a great opportunity to earn as you learn. See if you can find an apprenticeship as a junior 2D artist or 3D artist. Even if you can’t find a role in animation, if you keep up your passion for the industry, you might be able to transfer your skills into animation at a later point. Check out What’s an apprenticeship? to learn more about apprenticeships and find an apprenticeship to learn how to find one in your region, or approach companies directly.
