There are many ways to use the loopOut expression in your workflow, but we’ve prepared something new. Check the unique way to apply loopOut(“offset”) expression to your keyframes. Enjoy!

How to apply loopOut(“offset”) expression to your keyframes in After Effects

To apply the loopOut(“offset”) expression to your keyframes in software like After Effects, follow these steps:

  1. Select the layer containing the keyframes you want to apply the expression to.
  2. Open the “Expressions” section by clicking on the arrow next to the layer name.
  3. Locate the property that contains the keyframes you want to loop. For example, if you have position keyframes, you would find the “Position” property.
  4. Option 1: If the property does not have any existing expressions, simply click on the stopwatch icon next to the property name to enable expressions. Option 2: If the property already has an expression, hold down the Alt/Option key and click on the stopwatch icon to reveal the existing expression.
  5. With the expression editor open, enter the following expression: loopOut("offset"). Make sure to include the quotation marks around the word “offset”.
  6. Close the expression editor, and the keyframes will now loop using the loopOut(“offset”) expression.

The loopOut(“offset”) expression will cause the keyframes to repeat indefinitely, starting from the last keyframe and offsetting each repetition by the time between the first and last keyframes.
