This is a collection of useful expressions for Adobe After Effects that we use as a team.
The purpose, usage and required input parameters are documented in the Libraries themselves.
All expressions are formatted as AE-importable Code Libraries.
Here’s how you use it in your project:
- Download a Library File (e.g.
- Import the Library File into your After Effects Project
- Use this code snippet below to import the Library into the particular expression you are working on
- Call a function from the library
If you don’t like to use external files, we’ve included the Libraries in a pure .js form—you can always just copy and paste the functions you want to use from there. Using external files does have a few benefits, though: It’s slicker if you want to reuse expressions, easier to read and will increase performance. This is detailed in a blog entry from Motion Developer:
After effects pre-processes expressions to allow for ExtendScript backwards compatibility. This pre-processing isn’t done on code in external files, so there’s a performance improvement for long expressions when written in .jsx files.
