How To Loop Layers in Adobe After Effects CC 2018 - sometimes you just want to repeat the video or composition over and over again. Instead of duplicating it multiple times and sequencing it, you can actually use a simple expression.
Right-click the composition and and select "Time - Enable Time Remapping".
Now alt/opt + click the stopwatch and type "loopOut();"
This simple expression wil repeat the composition over and over again.
Sometimes you might get a glitch at the first repetition. In that case make sure you are using the keyframe before the last keyframe that has been set automatically. Just move the playhead over by Ctrl/Cmd + left arrow.
Now repeat the step with the expression and there you go. You've got a perfect loop.
