for some reason, I've never troubled myself with this before. My decks and system are all in alignment.
But I just notice that my Panasonic SDX is set with 7.5 as the default. I shot an interview, then went to dig, only to notice that it was darker. Looked under my 844 pref, and it's set to 0. So I brought it up to 7.5, looks closer to what I shot. Fine.
But now I bum-fuddled. Should I change my camera to 0 black level? Should I change 844x when dig in footage? And do I need to change the deck when I load a tape shot from that camera? Untimately, everthing should match, just not sure which way now? most of what I do ends up on DVD anyway, so I think mpeg is 0?
