Breathe…. Just export a self contained quicktime to your internal laptop hard drive. Plug the deck into the firewire port. Play back the quicktime off the lap top drive. It will work just fine.
Does your hard drive not have a firewire pass through port on it? It should. If it does, skip the above and plug in a deck/camera to record to miniDV.
Or burn a CD with the quicktime on it and give it to the dub house. They apparently have FCP, so they’ll be able to open a quicktime and output out of their fcp.
Since you’re only dealing with 30 seconds the options are limitless. You ftp them a file. At 5 minutes per gig DV goes a long way.
