Adobe After Effects CC 20202:
loopOout(“cycle”) or loopOut() expression

**Note:***: There is an 8-second audio error around the 2:20 mark. Sorry!


Note: The default loopOut express is “cycle” so if you want to use the loopOut(“cycle”) expression, you can type it as loopOut() without needing to type in “cycle”

This tutorial will show you how to enter the loopOut() expression that creates and endless loop looking at the first and last keyframes.
You can add the loopOut() expression on all animation properties (rotation, position, opacity scale…) and it will just loop the animation you created between the first and last keyframes.


The Expression Used in this Tutorial:
loopOut()
This can also be written as loopOut(“cycle”)

To Add An Expression:Press the Option or Alt Key and click on the Keyframe stopwatch
