Soundfx4, if you do not want to zoom in and want to leave the camera where it is then you won't have to fool around with focus much. But I would ask you, how fun will that be to watch? It is one thing to see an event in person from a distance but to watch on TV from a distance with the same shot for an hour or so. To me that is boring to watch.
I completely agree; I'd rather do it with something like four or five cameras that move and transition with the music etc (I know you all said two, not five. Five just sounds more fun
(I can't see doing it with 32 gig P2 cards at DVCPRO HD's bitrate, I'd probably need quite a few right?)
