Looping Multiple Layers with Different Lengths

[Walter Soyka]

[Eran Amir] “I am familiar with the loop expression, but haven’t found a way to apply it to multiple layers with different lengths without having to manually correct the time remapping keyframes for each layer.”

Instead of using loopOut, try the following expression for time-remapping:

// loop via time-remapping without adjusting default keyframes
if (numKeys < 2) value else {
timeInFrames = timeToFrames(key(1).value);
timeOutFrames = timeToFrames(key(2).value);
localTimeFrames = timeToFrames(time - inPoint);
framesToTime((localTimeFrames % (timeOutFrames-timeInFrames)) + timeInFrames);
}
