Premiere Pro Guru: Compositing and Masks

- Hi, I'm Luisa Winters. Welcome to Premiere Pro Guru: Compositing and Masks. At some point in our editing workflow, we will encounter the need for compositing and using masks, but what does that mean? Well, compositing and masking refer to making some parts of our clips transparent so that other clips can show through. Making the color green or blue into a transparent area is also known as keying. Think of the weatherman in front of a green screen. What the viewer actually sees is the weather map.

This is one of the most common examples of keying. In this title, we will go through native effects in Premiere Pro to accomplish our masking, keying, and compositing tasks. But what will we cover? Well, we will go through what alpha channels are, how to create them, and how to modify them. Then, we will cover using Ultra Key, which is an effect in Premiere Pro to key out green and blue color from your videos. Then we will cover Track Matte Keys, which will help you to affect moving parts of your clips. We will then discuss blending modes.

We will cover the different uses that we can give our compositing tools, from adding text or video to color correction and blurring of faces and things. The possibilities are endless, and sooner than later, you'll be incorporating these techniques into your workflow.
