Conforming vs Compositing: what's the difference?

These are two key VFX finishing steps, often confused. Conforming prepares the final timeline faithful to the edit; compositing creates and integrates the visual effects. They follow and complete each other.

Conforming: rebuilding the final base

Conforming means rebuilding the final sequence at full resolution from the approved edit. You gather the original source rushes and apply the exact cuts, transitions and edit effects. The result is a clean base, faithful to the edit, on which compositing and grading will build.

Compositing: assembling and creating the image

Compositing combines multiple visual sources — live action, green screen, 3D elements, matte paintings, 2D effects — into a single, believable image. The challenge is consistency: light, color, shadows, grain and perspective must all match for the illusion to be perfect.

Why they are complementary

Without clean conforming, compositing would build on an unstable base. Without compositing, conforming would remain a plain assembly with no effects. In Autodesk Flame, both flow within a single environment, which speeds up iterations and guarantees a consistent final render.

Concrete examples

12K conforming was central to SK-II – Pitera (giant screens), while multi-layer live action / 3D compositing dominates Chanel – Take Your Chance and Côte d'Or – Force de Caractère. Also read what a Flame Artist does.
