Quick Overview

Ease and Wizz is 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.

Introduction

Ease and Wizz is 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.

Usage

An Introduction to Ease and Wizz:

Simply select the properties that you wish to add expressions to, choose the type of easing from the popup menu, whether it should be "in", "out", or both and click Apply. As of version 1.1 it's possible to apply the expression to all keyframes instead of just the first two.

You can choose any number of properties (including different kinds), on any number of layers, and the script will add expressions to everything that's selected.

Note: If there are already expressions on the properties that are selected, they'll be replaced when you click Apply.

Types of easing

Regular easing (from most to least dramatic)
  • Expo, Circ, Quint, Quart, Quad, Sine
Special types
  • Back, Bounce, Elastic

FAQ

Since upgrading to CS6, After Effects crashes when I click “apply”. How come?
  • There is a bug fix update available from Adobe (more info here). Just upgrade your copy to 11.0.1 using Adobe Updater.

I’m unable to edit a mask path after applying Ease and Wizz with Curvaceous. What gives?
  • This seems to be a limitation with After Effects, and occurs when any expression is applied to the Mask Shape property. Temporarily disabling the expression with the “=” button will allow editing of the path.

How do I get more control over the bounce or elastic expressions?

  • These expressions are pretty speedy to apply, but don't offer too much in terms of customising. For that, I recommend checking out Dan Ebberts' motionscript.com. The Physical Simulations is a great jumping off point.

Why do I need to enable "Allow Scripts to Write Files and Access Network"?

  • The expressions themselves are separate files in the "easingExpressions" folder. The main script figures out which one you intend to use, opens the relevant file, and the applies the expression to all the properties you've got selected. In a pinch, you could also do this manually (but it's pretty laborious).

What's with the name?

Are these questions really "Frequently Asked"?
  • OK, you got me. They have, literally, never been asked.
