The effect in question is of making someones head blur back and forth inhumanly fast. Basically imagine someone turning their head, but missing a few frames, so their head is flashing back and forth...

How'd ya do it? Personally, I'd remove some frames in post, but then the body would move sightl still, right?

If you remove/speed up any frames from the actual footage, then the body would have to move as well because your cutting out a frame from the whole image. (unless the actor stood perfectly still while they turned their head). The only way i can think of to get around that is if you took the clip into after effects or some other post production program. You could create 2 instance of the same clip, and on the top one you could mask out everything but the actors head, then just speed up/ remove frames from that head clip. You would match this up with the shoulders on the original footage, and you'd have a sped up face but a regular speed body.

Awsome idea, many thanks!
