Thanks for your suggestion Shane but it did not work. Capture window still shows: Preview Disabled. While FCP controls the deck and sent it into capture mode, it never stops. Eventually I have to hit escape and have no video captured.
There are two reasons I would like to convert to DV for the offline. 1-To save drive space. This is a feature documentary with over thirty hours of interview material and probably another twenty of b-roll and other elements. 2-I have a production assistant writing transcripts with time code notes. I give the assistant a firewire drive packed with interviews and she takes them home to work on. While DVCPRO HD files are not enormous, they take up a lot more drive space than DV and require more processing power than I can expect from my assistant’s old laptop.
The issue of converting 60 frame material to a format such as DV that uses 30 frames is something I have never had to deal with before.
