How to Loop a Video File in After Effects

Every week, Frame.io Insider asks one of our expert contributors to share a tip, tool, or technique that they use all the time and couldn’t live without. This week, Laurence Grayson shares the simplest way to loop a video file in After Effects.


When you’ve been using After Effects for a while, it’s easy to forget that some of the basic functions and features you use every day aren’t always kept in obvious places. How to loop a video in After Effects definitely sits in this category. And looking at Google keyword data, you’re not alone in your search for this answer. 

On a side note, if you ended up here looking for how to loop a composition in After Effects, then you’re just a click away. And while it’s possible to use the composition looping technique to loop a video, there’s a much simpler way, and here it is.

Step by step

  1. Locate your media in the After Effects Project panel,
  2. Right-click and select Interpret Footage->Main (or use the Opt+Cmd/Ctrl+Alt+G keyboard shortcut),
  3. At the bottom of the Main Options tab, look for the Loop option under Other Options,
  4. Drop in a value that works for you, and hit OK.

This will come in handy for pre-rendered motion assets and animations like background plates.

Tip: Remember that you might need to increase the length of your composition to accommodate your new looping clip’s length. After Effects won’t automatically expand it for you. (Cmd/Ctrl+K, change duration).
