That is odd because that expression should evaluate to literally the exact same thing as your original expression 🙂

[Phil Rad] “I lengthened the animation out so it loops and it does it just fine but at every 40th frame, it disappears for one frame and loops again. I have no idea what is going on and it’s driving me nuts.”
Go to the last keyframe on the time-remapping property. Then go back one frame (a shortcut key for this is Page Up). Add a keyframe there then remove the last keyframe.
Make sure you do it in that order or it’ll mess up the time-remapping good.
As far as I can recall this issue never occurred in older versions of AE but appeared sometime around CS4… or maybe that’s just when I started noticing it 🙂
The last frame of a 40 frame composition is frame 39 (since the frames start from 0) but the time-remapping creates the last keyframe with a value of 40.
This behavior only causes problems with compositions as the last frame of a footage item (movie) is simply repeated once the time re-mapping moves beyond it.
To fully fix the loop you’ll also need to copy the first time-remapping keyframe and paste it one frame in front of itself.
Gee, while I’m thinking about this maybe I should file this as a bug 🙂

Tracking the screen will best be done with a planar tracker like that in Mocha AE. Planar tracks (like most tracks) tend to break down if there are a lot of reflections on the surface being tracked. If that’s the case then you may be better off manually corner pinning to the screen corners.

The QuickTime Animation codec can be lossless. The Lossless preset that ships with AE, for example, is lossless provided that you don’t wish to keep any more color information than 8 bits per channel. It does not introduce any compression artifacts at all.
As far as I know all ProRes variants are lossy to varying degrees. That said they can hold more than 8 bits per channel of color information as well.

What are the settings on the Random Effector? What are the dimensions of the Cube? And just to cover all my bases (I think) how is the Multishader applied (index ratio/intensity/etc)?

If you only want to randomly offset the followers in Z you could add something like this to the expression:
seedRandom(index, true);
min = -5;
max = 5;
z = random(min, max);
...current expression... + [0,0,z];The expression as you currently have it would go where it says “…current expression…”
The above would offset each follower by a random amount between -5 and 5 on the Z axis. This offset will be constant per layer.

[Lukasz Pason] “My question is how could you make the duplicates change their scale when they got closer or even change their opacity via expressions? Is that possible?”
The answer will change depending on the specifics of what you’re hoping to do.
For example, when you say “get closer” do you mean when any layer approaches any other layer’s position? Or only when a layer approaches the position of the layer below/above it in the timeline? Or when any layer gets closer to an arbitrary point?

Good God! Is Filip back?!
Welcome back Filip 🙂

Try this:
l = thisComp.layer("circle 3");
l.toWorld(l.anchorPoint);Darby Edelen

[Eran Amir] “I tried to test with 10 layers of HD video in an AE composition,
but very quickly I realized that is definately not the way to go.”Why did you come to that conclusion? Performance reasons or was execution difficult? It would help to know what issues you’re trying to avoid.
