Hi does someone know how to achieve the weird walking effect in the Icky thump music video when he is walking into the whore house looking drunk and wobbly.(1/3 through the video) Lots of parts in the video use this effect, but it's very noticable here.
I'm guessing they took off every 2nd or 3rd frame, and ramped it up a little/speed it up?

It looks like undercrank with some frames possibly removed to me. The crappy process work at the end after he leaves is awesome.
