The in-camera 16:9 squeeze of the DVX100A and B is 30% lower quality approx than the optical adaptor. That’s about it. Anything else is software scaling from 4:3 to 16:9 and also a massive scaling up to 1080i for the HDCAM frame size. I’d recommend a nice hardware upconvert or the Algolith plugin:
Unfortunately that’s normal in C4D- it only updates in the renders. Hopefully it will be addressed in a future update. If you search the boards you’ll find some workarounds.
That’s what I thought but I’ve gotten client burned DVDs in the past from standalones that I couldn’t do anything with- drag and drop, rip or dub. Weird.
