The group spin and the person spin were done mostly in camera. The group and person were put on top of a turntable and it's spun. Then in AE(or whatever editing program) the footage is sped up. In AE you can use time remap or use the time stretch parameter in your comp panel(have to expand the comp panel to access it).
