We have used our new HPX2000 on a couple out of town, multi-day shoots so far. We are shooting interviews in 720p, so we are filling cards pretty quickly. So it’s important that we be able to offload the footage from the cards while still shooting. We have an AG-HPG10 card reader that we can connect directly to a firewire hard drive and use as a firewire host, that works, but I’ve got into the habit of taking my Macbook on the shoot and actually opening the files in FCP before I reformat the card. As a bonus, If the client wants to see a quick edit, you can throw something together on the spot.
The AG-HPG10 runs for a long time on one battery charge. The Macbook does well without power for 3 hours or more, and we have a 160gb LaCie firewire powered portable hard drive that we transfer the footage to. This system seems to be working for us right now, but we are only one month into our new camera, and things evolve.
