Field dominance question urgent!!!

[Sean Oneil]

[Lars Bunch] “I spent months dealing with this stupid problem and what I finally discovered is that Compressor defaults to GUESSING the field dominence. And sometimes it doesn’t guess right.”

I’ve found this to be true if you use a QT file in Compressor. However, if you “Export to Compressor” directly from FCP, the field dominance will be correct.

I use P-JPEG for a lot of stuff. If I export a self-contained QT and open it in Compressor, it assume’s the wrong field dominance for some strange reason. But if I export it directly from FCP, it works fine.

so here’s the update if anyones interested

the new encode plays smoothly now in NTSC…but there are several “encoding errors’ with some heavy artifacts.

in general what is the hit rate of artifacts in mpeg conversion or is it possible to get perfectly clean files? I used compression markers for fast movement etc…

target 6.5 and max 8.0 and all the best settings in frames and resizing etc…

Try single pass CRB. VBR is broken in latest compressor is it not?

thanks graeme,

what would you suggest for target and maximum bit rate? all up there is about 50 mins of video split over 3 tracks + menus. are all the VBR settings broken or just the two pass VBR?

Try any of the “fast” presets, perhaps the “60minute” one?
