A set of expressions for After Effects that give you more ways to interpolate between values. The obvious use is in motion, but they can be used on animated properties of any kind. They’re applied with an After Effects-ish palette that can be docked, so it’s very easy to use.
A while back, Flash guru Robert Penner created a suite of extremely useful easing equations that have been used to build thousands of websites worldwide. I’ve adapted these equations to work as expressions in After Effects (for an introduction to After Effects expressions, check out Dan Ebberts’ excellent site).
One advantage of using an expression for easing is that the keyframes are editable. You can drag objects in the comp viewer, or move keyframes in the timeline, and the easing will be updated immediately.
