Looping a Precomp Between Defined Frames
Hi, I’m having trouble finding an expression that will loop a precomp between a defined start and end frame. I’m familiar with standard loop expressions like loopOut(“cycle”,1), but I really need something that will give me greater control. For example, start loop on frame [15] and loop back to frame 15 after frame [35].
Is this possible? Thanks!

Use Time Remapping [link] on your precomp layer, set the two keyframes you wish, then use loopOut() as you normally would.

Hey Walter, thanks for your reply. In this case I really need control over the start and end of the loop to exist entirely in the expression. The best I can do at the moment is use a modulo operator on time remapping (time % 30 would loop to the beginning every 30 seconds) but even this doesn’t give me control of the start frame of the loop. Maybe a while statement could do it? Thanks in advance. I’m just beginning to learn java so it’s hard for me to play around with it without getting syntax errors.

This expression will do what you want. Use it on the time-remapping property, and ask me questions about whatever isn’t clear:
var startFrame = 15;
var endFrame = 35;
framesToTime((timeToFrames(time) % (endFrame - startFrame + 1)) + startFrame);Walter Soyka
