I'm hard-pressed to see how. The blown-up data is properly interlaced at 60 fields per second, just like the PD150/VX2000, only it's much cleaner and with almost twice the vertical resolution. Looks good as video, and still frames extracted from the video look much better than similar still frames pulled from resized 4:3 and/or from the PD150 in 16:9. > Does Canon use the 1/2-line displaced green information when in 16:9 > mode? Canon does. Thus instead of interpolating each anamorphic field from a single field's worth of picture, the Canons can work with a full "pseudoframe" of picture. Hence the vast improvement in vertical resolution. Cheers, Adam Wilt (diese posts stammen von der DV-L Mailingliste - THX to Adam Wilt and Perry Mitchell :-) [up] |
