This tutorial shows a simple way to fix hard or unnatural edges on a keyed or rotoscoped subject using an edge matte. Even when the key itself is solid, edges can often feel too sharp, too clean, or disconnected from the background.
Instead of re-keying or blurring the entire matte, this method lets you target just the edges, giving you more control over how the subject blends into the scene.
You’ll learn how to:
Create an edge matte from an existing alpha
Soften or tighten edges without affecting the core key
Fix crunchy or overly sharp cut-outs
Improve how a subject sits in a composite
It’s a small adjustment, but one that makes a big difference in making your comps look more natural.
