Just the tip: "Utimate" guide to looping footage / compositions

I created this tutorial after spotting quite a few posts from people new to AE who didn’t know about the options. Then I started trying to come up with an utlimate, time-saving, plug-and-play expression that would take care of loop compositions for you.

And I succeeded!

(I know, it suprised me as well!)

Here’s the video which takes you through everything and underneath you find the expressions:

Project file:

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 > 10) {
} else if (CurrentLoopTimeAsPercentofOriginalPreComp > 90) {
} else {

Just the tip: White balance, scale and focus reference card for easy compositing

Here’s a short tutorial and giveaway of a digital (and physical) asset I use to help me composite greenscreened actors and CGI elements into a physical scene. This tutorial covers using the reference cards in Adobe After Effects, Video Copilot Element 3D and the included Lumetri Color, Camera Lens Blur and Match Grain effects.

I demonstrate how to composite the free Star Wars BB-8 model from VC’s Star Pack into a regular shot.


Video Copilot Star Pack:


Expression used to roll BB-8:





Xpos=thisComp.layer(“Element NULL”).transform.position[0]*-1;
scalePercent=thisComp.layer(“Element NULL”).transform.scale[0]/100;

Here you'll find a bunch of tutorials for using After Effects (mainly). I have a YouTube channel, called ShiveringCactus (long story - not funny anymore) where I post the videos.
