Manually drawing masks frame by frame to isolate a moving subject.
Rotoscoping traces around a subject across frames to separate it from its background when a clean key isn't possible. It is painstaking but powerful for cleanup, color isolation and compositing. Modern tools speed it up with tracking and AI assistance.
Masking and compositing are the skills that let you work on one part of a frame without touching the rest — and they open up nearly every advanced visual technique in editing.
Chroma key looks like magic on screen, but it is really a matter of physics, light, and methodical refinement in post.
