There's even ways to get After Effects to do the math for you, so in this lesson, I'm going to be showing you these introductory expressions that I think you'll find very useful. And as for the math part, we're talking about elementary school math, plus, minus, multiply, divide. However, there's a wide range of extremely useful expressions that you can use on almost any job that requires little or no programming on your part, and by programming I mean typing a word like wiggle, that's as hard as it is. And it is true that expressions are based on the JavaScript programming language.
I know a lot of artists are a bit intimidated by expressions because they associate them with programming and math. However there is another approach where you give After Effects more general instructions, such as this layer should follow what that layer is doing, but only do it half as much, well that's what expressions are, and they can come in extremely handy when you're trying to coordinate the movements of multiple parameters or multiple layers, or trying to accommodate client changes on a deadline. When it comes time to change the animation, you need to change the keyframes. You set up multiple keyframes across time and After Effects will interpolate in between them for you. Now normally the way you animate a layer in After Effects is you use keyframing, where you say at this time, this parameter takes on this value.
