How is it done - Plugin or prowess?

[dtzfilms]

Hi,
how do I do split screens and then have them move around either clockwise or anti-clockwise and finally have one screen fill the frame phasing the others out. I can think of an utterly silly way to do this but I'm sure there's a professional way to do it.

My silly way would be to resize and crop, then I'd be left with the movement - I'm guessing I'll need FCS Motion? - I'm going for a split screen, tri-screen, quad screen, rotate clockwise and back to one. I'm also trying to introduce a flicker as seen in this music video - is this a plugin or frame-splicing?

EDIT: I googled I found out that the flicker is a transition plugin by Alex4D it's called Premonition http://www.youtube.com/watch?v=mAkPyyTVj2U
just need to know if there's a plugin for split screens - ah - google that as well, but if you know, please help out.
Cheers!

Use the parameters of the Motion effect.
