Does anyone know how to do the skip frames like on preview panels?

[iwantaehelp]

So a month ago I didn't realize my project was skipping frames because of the preview panel. However I want to know how to skip frames as an effect?

Posterize Time. Pre-compose, slow down the frame rate of the Pre-comp, open the Pre-comp Settings/Advanced tab and select Preserve Frame Rate when nested or in render queue. 

Those are probably the easiest solutions. If you pre-compose and the main comp is 30 fps, and the pre-comp (nested comp) has the frame rate set to 15, you will only see every other frame because each frame will play twice as long as you do not turn on Collapse Transformations. Did you follow that? It's just math. You can play every other frame, every third frame, or every fourth frame if you just divide the frame rate of the nested comp by the number of frames you want to skip.
