How to make Glitch Effect on Alight Motion

Displacement Map is great for building a variety of glitch effects. Here's just one example:

To make this effect, we first made the RGB separation (this is optional) by creating three identical text layers. We then made one layer red (with a screen blending mode), one layer blue (also with a screen blending mode) and the original layer white. The red and blue layers were then animated to create a simple RGB separation:

We then created a map layer using just a blank square shape, with a series of effects applied to it:

• Clouds (with keyframe animation for the postition)
• Mosaic (with a large square size)
• Mosaic (a second time, with a smaller square size)
• Noise (with "Freeze" turned on and "Amount" set quite low)

This was then grouped and the group was stretched out horizontally to make the mosaic tiles wider rather than square. This resulted in a map layer that looked like this:

The flickering is because of the animation on the Clouds effect (it moves so fast the change appears random).

This map layer is then placed in front of the three text layers, and Displacement Map is applied, using keyframe animation to increase and then decrease the offset over time.
