If your intent is to go to DVD, avoiding rendering audio is a big plus. If your camera can record in 16 bit 48KHz, keep this depth all the way through your project. Digital re-rendering from low to high is the sort of thing that makes audio engineers cringe. Even the state of the art in "up-rezzing" creates digital sonic impurities, which, while often negligible, in bad cases is atrocious. We never have any troubles here even with a bunch of 48KHz tracks, either on a TiBook, or on our desktop editors. Were it only that music libraries thought in 48KHz. Richard Brown
