IntroductionEase 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
UsageAn 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 easingRegular easing (from most to least dramatic)
- Expo, Circ, Quint, Quart, Quad, Sine
- Back, Bounce, Elastic
FAQSince 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.
- 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?
- It's a pun on a song title by UK band Pulp: "Sorted for E's & Wizz".
- OK, you got me. They have, literally, never been asked.
|After Effects||CC, CS6, CS5.5, CS5, CS4, CS3|
2013.07.14 - Version 2.0.4
- [FIXED] Reinstated the graceful catch for errors when applying expression to mask path without Curvaceous turned on.
- [FIXED] Put global variables on a custom object and renamed functions to avoid namespace clashes.
- [FIXED] Caught a bug that left the easing-type popup blank if selecting Curvaceous when Elastic or Back were selected. Now it defaults to Expo.
- [CHANGED] Removed the requirement in the documentation to “Allow scripts to write files and access network”.
- [CHANGED] The default period when using Elastic easing is now 0.81, rather than 0.8 (which may have been related to a rare rounding error).
- [FIXED] Reverted the type in the popup menus to a black colour, as it was illegible in CS5.
- [FIXED] The inBounce behaviour was, inexplicably, identical to the outBounce behaviour. It now behaves as advertised.
- [NEW] The popup menus and the “Curvaceous” checkbox now have tooltips for extra information.
- [CHANGED] A minor tweak to add compatibility with Expression Toolbox.
- [FIXED] Added a more graceful catch if you try to add an expression to a mask path without the "Curvaceous" checkbox enabled.
- [NEW] Curvaceous. Allows you to apply easing expressions to curved motion paths, and to mask or shape layer paths.
- [FIXED] After Effects CS4 compatability.
- [NEW] Tooltips added to the palette
- [NEW] Popup menu added so you can select which keyframes to affect (all, first two and last two, or just the first two)
- [CHANGED] Replaced the "type" radio buttons with a popup menu
- [CHANGED] Eliminated need to choose easingExpressions folder path (thanks to Jeff Almasol)
- [FIXED] Fixed colour of text in popup menus - thanks to Jeff again
- Initial release
