if you want a property to animate on 2's or 4's like they do in cel animation. Set some keyframes and apply this expression. It should work on any property.

Code: Select all

animateon=2;   //as in animate on 2's or 4's
framerate=(1/thisComp.frameDuration)/animateon;
valueAtTime((Math.round(time*framerate))/framerate)

You can also use posterizeTime()

Code: Select all

animateon=4;   //as in animate on 2's or 4's 
framerate=(1/thisComp.frameDuration)/animateon; 
posterizeTime(framerate);
value;

This is a great script... any advice on how I can apply this to the shape property of a roto mask? I'm doing a stop motion, and rig removal on twos is very cumbersome.
thanks!

No script necessary. Change the frame rate of your comp to half your current fps. If you nest this comp in another comp, make sure you check the "preserve frame rate in nested comps" option in the Comp Settings.
