Your best bet would be to get in touch with the vendor that will actually do your film recording. Find out from them their specs. Theoretically, the resolution of HDTV is similar to that of 35MM film, but there are so many factors that will come into play at the transfer house. The one thing I can tell you that's a constant is that 35MM film runs at 24 FPS. That'll save some time on the render.... Hope this is helpful. - Dex
