Yes, all of these could definitely be coded into an AE expression...there are actually a ton of types of interpolation methods out there...spline based interpolation, polynomial based, lerp, cosine, etc. Maybe sometime in the next two weeks I'll get some time to code a few of these, I can see a few ...

Thanks Lloyd, this is a very usefull script... especially for those without the $ to buy Nucleo. Why no source code this time around however?

Here are a few free expression tutorials:

Enjoy.

initialVeloc = 93; simSpeed = 7; gravity = 9.8; launchAngle = 70; launchPoint = [ 72 , 452 ]; //--------- t = time * simSpeed; a = [ 0 , gravity ]; initialVx = initialVeloc * Math.cos( degreesToRadians( launchAngle) ); initialVy = initialVeloc * Math.sin( degreesToRadians(- launchAngle) ); v = [ t ...

I have a project in which I did just this...I finished it a few days ago. I used 2 expressions. One expression places the layers in a grid, and the other one uses sampleImage to sample pixels from a movie layer and use this to drive the color parameter of the "fill" effect. The project use...

Hello everyone, I have been working on a standalone render manager app for compositors/motion graphics artists/3d artists. Here is a thread about it on creativecow.net. http://forums.creativecow.net/readpost/2/903505? I would really appreciate some input form some of the technically minded people wh...

I've recently been working on a standalone render automation program ive written in Java. This might be useful to you. It works fine on Windows right now, I'm just fixing up some UI issues and adding a few features before I put it online somewhere. This program can be used to schedule After Effects ...

Try this instead:

After recently rendering something, only to realize I left a few layers on draft quality, I decided to create a script that could turn on certain settings througout a slected comp, and it's nested comps. This script uses a UI and allows users to specify if they want Best quality for all layers, to s...

Since I don't have AE 7 yet and can't seem to find the new scripting guide online, anyone care to tell me what iconButtons are? Also, what is this system.callSystem() you mentioned in your previous post? Thanks for the info.

Thanks for the info. After reading the Scripting Gude I thought procomposing was the only way to go too but I was hoping one of you guys might have known some method I overlooked

Anyone know how to replace a simple way to replace a layer in a comp with a footageItem.(like what happens when you alt drag a piece of footage onto a layer)? I looked through the scripting guide and can't seem to find a simple way to do this.

It's called the modulus (spelling?) operator. It's pretty much just means "the remainder of the division of the two numbers."
