Are you running Mac OS or Windows? From what I know, DVCPRO HD is a Mac proprietary format included with FCP Studio 2, so if you’re rendering from a PC or an older version of FCP, you’re stuck with whatever HD formats your system has installed. I’m assuming though that you’re on a Mac since I’ve never come across DVC anything whilst exporting in the PC world. In whichever case, if it’s not installed, you’ve got to find another format. The Avid DnxHD codec is pretty good and should be roughly comparable in file size, though I’ve had problems with alpha channels when rendering from non-Avid apps.
