I just Finished a 2 minute clip DVC Pro HD/30pn with my HPX 170. Some clips were Over cranked at 48 frames per second. I used Adobe Premiere CS4 just as a test. When I exported, it took over an hour to export the 2 minute clip. Nothing special other than a few transitions and the slow mo from the camera. This is the first I have used DVC PRO HD/30 pn with a P2 camera. I mostly use standard Definition that renders and exports quickly with this system. I have a decent computer but I thought the time to export is rather long. I wonder if it's my video card? Does anybody know if there is something I'm doing wrong?
