Welcome to a new series of how-to videos about Adobe’s popular After Effects program!

In this first how-to, DMA instructor Damien Verrett shows you how to key your green screen footage in After Effects. In this case, the footage is “less than ideal,” and Damien shows you how to work around those limitations.

What do you do when your green screen footage is far from perfect? Damien Verrett knows!

Damien shows you how to adjust color saturations, as well as how to use “garbage” mattes and when to use Clip Black and Clip White when you need to work in solid black or white. Plus, Damien demonstrates using the Keylight effect and other keying effects.

Covered in this DMA how-to tutorial:

  • Pre-composing effects to keep them better organized.
  • Tweaking colors with the master saturation slider.
  • How to work in alpha layers, using monochromatics.
  • Toggling the transparency grid to check your results.


In this DMA How-To, Damien Verrett goes into detail in how he works some not-so-ideal green screen footage into the perfect shot for a music video he’s making. You’ll learn how to perfectly key your own green screen footage and develop a nice workflow.

This summer, why not consider getting a full week’s worth of production experience at one of DMA’s video production tech camps? Our summer camp season will be in session soon, but there are still spaces available in certain classes.
