Blur transition, production/post production tracking...I'm stumped!

Hey everyone,
So I need help in understanding what this effect is.

At first I thought it might be some manipulation of still images (taken from the live action footage) as well as blur added to stop the audience seeing the but after having watched it almost frame by frame I figured there was clearly post production digital zoom, having seen the MTV Making Of I know the mirror was blue screen.

However, the camera movements around the singer are what most fascinates me. I’m tempted to think that it was motion control (the director Dave Meyers is fan of that) but why other than to get the computer precision with your shots. Anyway- motion control or not if anyone knows how this may have been done in production as well as the post production phase I would love to hear from you! If I know how it was done the expensive way I can figure out how to do it on the cheap…

Many Thanks in advance!
