My full After Effects course: https://www.udemy.com/aftereffects-beginners-complete/?couponCode=YT10

With this tutorial I want to explain you what is a Track Matte in After Effects and how to use it. To make things simplier I compare Track Mattes from Adobe After Effects CC to Masks in Photoshop (because more people know what this is in comparsion to track mattes) and then show you an example in-program. Learn in a few minutes how track mattes are used in the program and what can be achieved with them. I go step by step showing you Alpha Matte, Alpha Matte Inverted, Luma Matte and Luma Matte Inverted.
