In traditional animation, this was called tweening, but we just call it awesome.Īfter effects expressions can be used to modify animations in the tweening process or to set values of properties based on other factors. The program automatically changes the scale between the keyframes, so you don’t have to do it automatically. For example, animating the scale of a graphic from 0 to 100 takes two keyframes, one set to 0% and one set to 100%. If you’re unfamiliar, a keyframe in animation is a point in the timeline where a property changes. It’s a very versatile tool that allows anyone with a passing understanding of Photoshop or Illustrator to jump in and start animating, and one of the things that makes it so versatile is the ability to apply expressions.Īfter effects expressions are bits of code that are written in JavaScript and can be applied to any parameter that you can keyframe.
We use After Effects expressions for all of our video graphics.
