how is this done?

I saw this music video:

http://vimeo.com/13894031

and I have no idea how it is done, moving shapes that hold a video sequence..


any help would be great, thanks in advance

 

well... at the moment I am using SonyVegas Pro

but am getting my macbook pro in two weeks and will follow with either the adobe suite or FCS.

Do you figure the animated mask layers animated with Motion?
Alternatively, what FCP plug-ins are used?

I am trying to find information and/or tutorials on google but no dice.

Any help is greatly appreciated

 

In your opinion, would it be best to use Adobe suite and make the animation in Flash and work from there...?
Or, will motion allow me to make an animation similar to the one in that music video?

Once the animation is done, is it quite simple to bring the vector into the editing suite, and convert it to a mask and go from there?
