![]() The variable “freq” is the frequency, or how frequently the bounce occurs. Modify “amp” for the amplitude or how much bounce is present. Nonetheless, it’s a great helper and I use it all the time. Although I’ve made a slight modification to it to make it a little more user friendly, it’s nothing that I will lay claim to as my own code. The seeds were certainly planted by the great Dan Ebberts, and then a modified version was posted on. It’s very cool! This expression is a bit of a community effort. This also accounts for scalar or array values, so you’ll find that this expression works just as well on 2D rotation as it does on 3D position. ![]() Being that true “velocity” includes the vector (or traveling direction in 3D space), the bounce happens in whatever direction the object is traveling. Intertial Bounce v1.2Įssentially, Inertial Bounce creates a bouncing motion of any parameter from one keyframe to the next, based on its velocity. ![]() These are expressions I use in just about every project, and I consider them to be incredible workflow enhancements.ĭownload the AE Presets 1. Therefore, I’d like to share with you my 5 favorite expressions. I realize that expressions can be daunting, and some would rather copy and past useful code rather than learn the language.
