That makes sense about the blend vs discard fields. I understand now. Is there anything I can do about the PDI captures at half size display to discard one field rather than blend them? I don't mean discard half the video for real, just when it's previewed at half size.
So for rendering a final avi, I just have to select the option "lossless huffyuv"? I'm not sure that will be selectable under "Render As" in Vegas. Won't I need to do something first?
About adjusting calibration levels. What should I look at on the screen to determine true black and white? Is there some kind of grayscale or color window because I don't remember seeing one? What do you mean by white not clipping?
And lastly, is there anything that can be done about the picture being shifted up (and having a slight bit at the top cut off) in the PDI captures?
