Introduction to Rotoscoping in After Effects

In this After effects tutorial we'll learn the basics of Rotoscoping using After Effects. Digital rotoscoping is the process of creating a mask or matte to isolate part of an image or video so you can change it or add it to a different background and is a very important part of the visual effects process. We'll begin this tutorial by learning about the pen tool, which lets us draw shapes and masks. We'll then dive deeper into the masking system in After Effects and learn some time saving workflows for checking your roto. We'll then jump into the basic workflows of animating masks and how we can keep a consistent shape for a more appealing matte. We'll end by outputting our mask into an image sequence that can be used in other applications.
