I need to know if Black Magic captured/encoded videos could be use in Mac DVD Studio Pro.... I'm having problem maintaining a good quality picture when I'm authoring DVD using a sequence that was down converted from HD to SD... In the Final Cut sequence, the picture look great just like the original HD. I use the HD IO AJA Box / Apple Pro Res422 setting in Final Cut Pro. But when I import the footage in DVD Studio Pro, I get macro-blocking (very noticeable during scenes with camera panning, moving water, pretty much every time there's moving images and camera panning.... I don't see it in the Final Cut session, only when I import it to DVD Studio Pro.... I never had this problem before and I've done many DVD.... It's only now that I'm getting SD masters down converted from HD.... I have no clue what's going on! Help!
