ABSTRACT
To follow along with me, open up the Color Difference Key.aep project from the Chapter 10 folder of the exercise fi les. For this project, we’ll be using a photo rather than a video. This effect does much better with lightly-compressed or noncompressed video. And since those are more challenging to distribute, and we’re only using one frame anyway, we’re using a photo. Apply the Color Difference Key effect to the Chad Key layer in the Chad Key comp.
