In this series of lessons, we’ll be learning how to use the Roto Brush Tool.

A lot of people try to use the Roto Brush Tool without knowing how it works.

They jump in, start painting one frame after the other and depending on their patience level, they soon give up.

This is because there are a few ground rules for using this tool, and if you don’t know them, your matte will not turn out well. If you understand the ground rules, then you don’t need to be a certified “Roto Brush Tool Expert” to use it. This tool is meant to speed up

your workflow. With that being said, this training doesn’t use footage examples that are unrealistically easy to roto. So, after we get a basic understanding of this tool, we are going to have some hard lessons with uncooperative footage that will help you learn the real

challenges of using this tool.

As well as, some of the perfect places to use it and how to trick your footage into looking just as you envisioned, with a combination of techniques.
