We use the XDCam and connect to the PDW-F70 deck via firewire. We researched the cost for importing and using firewire and found that with an FTP application, like Cyberduck (which is a free app) and the Sony XDCAM transfer application we could import footage from the disc without having to purchase the Flip4Mac software (about $500 a seat and we have 10 seats).
The deck has a series of settings to set up your network. You should set the ip for the deck, the subnet mask for the deck, and determine whether the deck is going to be managed via DHCP. We have ours setup with DHCP turned off and manually configured our ip and subnet mask. Once the deck is properly configured, set the deck to network using the switch on the front of the deck.
From the computer you want to access the deck, open your FTP application and connect to the deck using the ip address. Ours is set to 192.168.3.107. The username and password are deck specific. The username is usually admin and the password is usually the deck model number. We have the PDW-F70 decks, so our login is username: admin and password: pdw-f70.
Once connected to the deck, copy all the information from the disk to a folder on your computer, SAN, or other storage location. You then import footage into FCP using the XDCam transfer software provided by Sony. From FCP, you choose file>import>XDCAM and the transfer program launches. You add the folder you copied the data and files to and log and import footage as normal.
We have found that this workflow allows us to import footage from XDCam much faster than real time and it saved our company about $5,000.00.
