Ease and Wizz 2.0 — now hosted at aescripts.com
After Effects scripting guru Lloyd Alvarez is kindly hosting Ease and Wizz at his ridiculously useful site, aescripts.com. Ease and Wizz will continue to be free and open, but donations are gratefully received if you find it useful, particularly if you use it in a commercial capacity. Thanks!
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.
Ease and Wizz has been reviewed by these good folk:
- Alan Shisko on Motion Graphics ‘n’ Such
- Chris Meyer on Provideo Coalition: Creating Motion Graphics
- John Dickinson on Motionworks
Download
You can download Ease and Wizz from aescripts.com.
System requirements
- Adobe After Effects CS3 through to CS6.
- Mac OS X or Windows.
Installation
Gyorfi Szilard has very kindly put together a comprehensive screencast guide to installing Ease and Wizz on Windows Vista. If you’re on Windows, I encourage you to check it out. Otherwise, cross-platform instructions are below.
- Open the After Effects preferences. Check that "Allow Scripts to Write Files and Access Network" is enabled.
-
Navigate to the After Effects Scripts folder. On my Mac it’s here:
/Applications/Adobe After Effects CS6/Scripts/
On Windows:C:\Program Files\Adobe\Adobe After Effects CS6\Support Files\Scripts\
- Create a folder in Scripts called "ScriptUI Panels" (if there isn't one already; I think AE CS4 might come with one conveniently made for you).
- Extract the zip archive into the ScriptUI Panels folder. It should look something like this:
- Relaunch After Effects. There should be a new item under the Windows menu, right at the bottom: "Ease and Wizz.jsx". When you select this item, a new panel should appear. You can dock it with some other panels, wherever's convenient.
- Create a new comp and put something in there (shape layer, bitmap, solid etc.). Animate one of its properties, such as position or scale. With at least one keyframe selected, select the "Apply" button on the Ease and Wizz palette.
If you’re still stuck, you can watch the hilariously amateur screencast I’ve put together. Note that there’s no sound. Important: the screencast is for version 1.0 of Ease and Wizz. The palette layout has changed, and you no longer have to locate the easingExpressions folder.
Usage
You can kick back and watch this screencast, or scroll down for a more literary overview.
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.
- 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.
- After Effects CS4 crashes every time I quit. Coincidence?
- It’s an After Effects bug that’s been acknowledged by Adobe. Presumably they have a crack team of highly trained programmers working on it as we speak (er, type).
- Can I use this with After Effects 7?
- I never had any joy getting the palette to work in AE7. However, you can always just copy and paste the expressions directly into the property you're animating … if, for example you wanted an expo in-out tween on a position property, keyframe it as usual then open the file "inOutExpo-easeandwizz-all.js". Copy the contents, add an expression to the position property, then paste it in.
- 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?
- It's a pun on a song title by UK band Pulp: “Sorted for E's & Wizz”.
- I’d like to give you some money. Can I?
- Hell yeah! Just click this big ugly yellow button and PayPal will do the rest:
- Are these questions really “Frequently Asked”?
- OK, you got me. They have, literally, never been asked.
