Wow! you are right, when I tested the expression i posted in this thread I did it in CS5 and it worked fine but when I just tried it in CS4 it doesn’t work. I can’t believe I didn’t know about this, thanks for pointing it out. I am assuming that since it is fixed in CS5 it was a known bug.

Hey Dan,
What do you mean by temperamental? I’ve never had any issues with posterizeTime.

You need to apply that expression to the position property. Alt-click on the timewatch icon for position and copy and paste the expression into the text field that opens.
The shortcut to add a keyframe for position is Alt-P

frameInterval = 3;
fps= 1.0 / thisComp.frameDuration;
posterizeTime(fps/frameInterval);

I also just finished teaching an intro to after effects scripting course at fx-phd. If there is enough interest they will run the course again so send them an email to let them know.

Using expressions is not the most efficient way to do this since expressions are evaluated for every
layer at every frame. This is why I wrote a script to do this. The script only
needs to he evaluated once at run time. https://aescripts.com/3d-layer-distributor/Lloyd
