Cinecom.net: Create a glitch (distortion) effect in Premiere Pro
In this tutorial, Jordy Vandeput of Cinecom.net shows how to create a glitchy distortion effect inside Premiere Pro. Learn how to use the Color Balance (RGB) effect to separate the red, green and blue channels, and then use blend modes to make your shot look like it's tearing apart at the seams! Remember, you can save your glitchy distortion effect as a preset to use over and over again.
The glitch effect is something very popular that is usually created inside After Effects. Some third party plugins even allow many customization. But the glitch effect is actually not that hard to create, that’s why we’re letting Premiere Pro shine again. —Jordy Vandeput, Cinecom
