Visual Effects — Compositing Basics
Learning Objective
Learn the basics of compositing: green screen keying, masking, and tracking.
This Week
Compositing is the art of combining multiple visual elements into a single image. The most common compositing technique is green screen keying — replacing a green background with a different image or video. This week, you will learn the basics of green screen keying, masking, and tracking.
Daily Practice
Practice green screen keying on a short clip. Focus on getting a clean key — no green fringing, no edge artifacts. (45–60 min)
Weekly Challenge
Practice green screen keying: composite a subject against a new background. The composite should look realistic and seamless.
