i guess i would like to add my 2 cents of information in regards to this effect, i was watching the making of a scary movie called the messengers and in one scene the kid crawls on the ceiling in that same style and in the making of featurette the technical director stated that it was shot at 6 frames per second and i know that after effects comes with a plug in which can cut frames, so give it a try and let me know if that would work.

Andrew kramer has a tutorial on frame rate conversion maybe that can start you off here’s the link. https://forums.creativecow.net/articles/kramer_andrew/fps/index.htm
where he has some presets and i believe the name of the plugin that would allow you to do that in AE is posterize time.

so there you go, hope this helps some.
