The pre-expression value of any property can be accessed within an expression using the attribute value. The highlight color of the property's value in the UI indicates whether the property is using a pre-expression or post-expression value pre-expression values are blue, while post-expression values are red. These pre-expression values can then be modified or used by an expression, just as an effect changes or uses the pixels of a layer, resulting in the post-expression value. You can think of pre-expression values as similar to a layer's pixels without any effects applied. The pre-expression value is simply the value of the property before any expression is applied, either static or animated by keyframes. Here's a basic example of looping with expressions:Īll properties in After Effects that can be animated have a pre-expression value and a post-expression value. If you want to know more about it, see Understanding the Expressions language. You can create expressions by using the pick whip or by copying simple examples and modifying them to suit your needs. The expressions language is based on the standard JavaScript language, but you do not need to know JavaScript to get started with expressions. Rather than animating the Position property with keyframes, you can apply a wiggle expression to it. For example, you have a ball moving across the screen from left to right, but you also want that ball to wiggle. Unlike a script, which tells the application to do something, an expression tells a property to do something.

When you want to create and link complex animations, but want to avoid creating tens or hundreds of keyframes by hand, try using expressions. An expression is small piece of JavaScript code that you can plug into animated properties in your After Effects projects, that evaluate to a single value for a single layer property at a specific point in time.
