Here's the "ultimate" guide to looping footage and compositions in Adobe After Effects.
In this quick tutorial, I cover Interpretation, Time Remapping and share my own expressions to auto-loop and automatically crossfade so that you get a really easy way to loop videos and comps.

Expressions used:
Basic method for Time Remapping: loopOut()
Ultimate method
Time Remapping:
tEnd = timeRemap.key(2);
loopOutDuration(type = "cycle", duration = tEnd*1.8)
For auto-fading opacity:
t = timeRemap;
tEnd = t.key(2);
OriginalLengthofPreComp = tEnd.value;
CurrentLoopTimeAsPercentofOriginalPreComp = t*100/OriginalLengthofPreComp;
if (CurrentLoopTimeAsPercentofOriginalPreComp [LESS THAN SIGN*] 10) {
CurrentLoopTimeAsPercentofOriginalPreComp*10;
} else if (CurrentLoopTimeAsPercentofOriginalPreComp [MORE THAN SIGN*] 90) {
linear(CurrentLoopTimeAsPercentofOriginalPreComp,90,100,100,0)
} else {
100
}
*[MORE THAN SIGN] - YouTube descriptions don't allow angled brackets. Replace everything, including the square brackets with the right-pointing chevron thingy
