Compositing
Compositing is the post-production process of combining multiple visual elements (renders, plates, effects, and graphics) into a single final frame for an animation or live-action shot.
This is where the look comes together. Compositors balance colours, add blurs, and integrate all elements so they feel like they exist in the same space. It is a critical stage in Myth Studio's advertising and TV production pipeline.

Frequently asked questions
What software is used for compositing?
Most studios use Nuke for high-end work, particularly on live-action and VFX, and After Effects for motion design and shorter-form animation. Both let the compositor stack rendered passes (beauty, shadow, reflection, depth), apply colour grading, integrate effects, and output the final master file. The choice depends on the kind of project, not on personal preference.
Why are render passes used instead of one final image?
Because compositing in passes (separating beauty, shadow, reflection, depth, ambient occlusion, and so on) gives the compositor control without re-rendering. They can change shadow intensity, swap a background, or tweak a colour without going back to the 3D lighter, which would cost hours per shot. It is the standard production approach for any meaningful 3D work.
How is AI changing compositing?
AI tools are starting to assist with rotoscoping, auto-keying green screen, denoising, and upscaling, all the slow manual cleanup work. The creative parts (colour grading, mood, integration of CG into a plate) still need a compositor. We use AI inside our AI-assisted animation workflow to remove the slowest steps and free time for the creative passes.
