I'm shooting video of a high school musical this weekend and would like to record directly to hard drives rather than tapes to save time logging video and re-synching audio. I have access to a powerbook but it doesnt have enough hard drive space. However, I have a 30GB iPod video that I'd like to record to. Since firewire has a higher sustained transfer rate, can I use my old firewire cable from my 3G ipod with the new one and record video to the iPod in real time from the camera? I would need to record for 22.5 hours straight. Has anyone successfully done this?
