Thanks everyone for the responses,
I also think it’s a field order problem. In response to Floh, I’m using NTSC.
I’m exporting reference movies from a range in Media 100 (which greys out the field order option). and then booting into a separate drive to use Compressor and DVSP.
In compressor, I use the “DVD Best Quality 90 minutes” setting which includes MPEG-2 6.2 Mbps 2-pass. I applied this to a short reference movie made from a 20-sec range (out of 30 minute program). The default for field dominance in the A/V attributes box is “Bottom First.” When burned with DVSP, this looks perfect.
However when I export a range of the full length program, the field dominance defaults to progressive. I can change it manually to bottom first, but when burned, it looks horrible.
The media 100 program includes some Boris Graffiti titles and quicktimes imported from After Effects so I created various short reference movies that included those elements (in case they were screwing it up), but they all default to “bottom first.” (which works) Only the full length program is messed up.
Any ideas? Thanks again!
