  Simple but frustrating loop question

  Posted by Mike Cantor on February 1, 2014 at 7:45 pm

  Hi folks, I have watched a zillion tutorials on how to out a loopIn or loopOut expression on Time Remap to loop a clip but still can’t solve what seems like it should be a simple problem.

  In all these tutorials they loop a clip from beginning to end. In my case I have want to loop a certain segment of a larger clip, say from frame A to frame B, over and over.

  I put two Time Remap keyframes at A and B and the expression “loopIn(type = “cycle”, numKeyFrame = 2);” This doesn’t work. I’ve tried every combination of loopIn, loopOut, and numKeyframe and can’t get it to work . Can someone tell me what I’m missing?

  Thanks a bunch,
  -Mike

  loopIn(type = "cycle", numKeyFrame = 2)

  I’m not sure exactly how you have things set up, but this example might help. If you set the two keyframes you want, then delete the two keyframes that AE created when you turned on time remapping, something like this should loop the section you want:

  if (time < (key(1).time + key(2).time)/2)
  loopIn()
  else
  loopOut()

  Thanks Dan! After writing the post I found a plug-in that writes the expression for you as well as gives you some other options:
