MPEG2 brightness/contrast question I should have asked 6 years ago.
This is a real basic question I wondered about years ago but never bothered asking. Whenever I output any project from sources ranging from scanned jpeg’s to HDV, in any program from Vegas 6 to 10, the mpeg2 seems to change the contrast just a bit from the preview window when I’m editing. The brighter whites will get slightly brighter and lose some detail and the darks look just a tad darker. It’s never been a huge issue and it’ll rarely cause me to go back and make clips darker than they should be just so they render out properly, but I was wondering if this is just something Vegas always does, or is it a setting somewhere, or just something with the NTSC standard itself that needs things to be in a certain range?
One thing I can say is that when I go to render mpeg2, I’ve never messed with any settings on the Advanced Video tab, and I’ve always left “Profile” and “Level” on the regular video tab set to “Main” Would any of these settings affect this issue? Does everyone use the Allow field-based motion compensation option? I always have and I find that the editors here who use FCP have a lot of jagged edges when dumping 1080i footage to DVD and I’ve never had that issue, but I think my video may be just a tad softer, so I was thinking that may be what that option does.
