Hi, I was just offered a great deal on an HVX and am looking at the practical aspect of using an HVX to shoot a documentary. I'm going to be in Scotland shooting with a somewhat new MacBook (would give you more specs but since its not my computer, I dont have them available at the moment) for offloading. But would the HVX with a 16gb, 8gb, and 4gb p2 allow me to shoot enough without major pauses for unloading? I suppose the more proper question is with a MacBook can I unload and keep shooting at the same time even if I had to do the unloading with firewire? (Unless new-ish MacBooks have the necessary card slot for p2). I also would like to know if I can hotswap the cards. My other option is shooting with HDV, but if I can make a P2 workflow work, that would be ideal. Most of my interviews are scheduled for about an hour so I'd like to be able to keep shooting constantly while unloading and swapping out the cards.
