I'm trying to render 3 minute section of my completed V.V. movie to mov. format so that it will play in Quicktime. It takes hours to process, then I get the error message that "Unknown error" has occurred during the processing. The same file renders for DV-output just fine. I know it's not rendering to mov. because when I reinitiate the process after the error message, it still takes hours. What's wrong with this picture? ALSO How do I burn a DVD from my V.V. Movie?
