Forcing a comp to play back at a certain framerate in aftereffects I have an after effects comp that is "stop motion", i.e. all animations move at about 8 frames per second.

I want to use this comp as a 3D layer and animate camera moves over it smoothly at 30 fps, while the animation continues to play at 8 fps.

But every time I drop the 8 fps comp into the 30 fps comp it seems to be rendering at 30 fps, losing my stop motion effect completely.

I have a video example here: 
                
            

Will I have to render out a .mov and reimport to get the desired effect?
Oh my goodness after ages I found it.
