Set Matte Versus Track Matte
Set-Matte is a more versatile and “advanced” way to get the most out of working with mattes.
Mike Ridolfi from Mobox Graphics shows you how to use the built in Set-Matte effect inside After Effects to set mattes for multiple layers without relying on track mattes. This makes for a slimmer project file when working with multiple mattes. He discusses the different types of mattes too; such as alpha matte, alpha inverted matte, luma matte, and luma inverted matte.
