Loop count in video clip settings, how to apply changes to composition? I created a grid of about 50 videos. I want them all to loop so I changed the loop count of the videos via Interpret Footage &gt; Main... &gt; Loop. The changes show up in the timeline, but they are not applied. When I let it preview it, the videos only run once.

I don't want to add those 50 clips again to the composition and apply the transforms.
I'm guessing your videos are of different durations. If no, just precompose the grid layers and loop that composition. If yes, worst case scenario is to precompose each video layer and loop those.
