More serrated SD downconvert

[Tom Brooks]

George,
My experience with HD has been 720 60p (59.94 that is) thus far. It was shot with a Panasonic HVX-200 on P2 media, so it’s true progressive at 59.94fps. The downconvert to SD 29.97 does show the jaggies only when the subject or camera is in motion and only certain types of subject matter. It only shows up on hard-edged diagonal lines. The jaggies go away when the timeline is paused. The jaggies only show up on an interlaced display, not on thePanasonic TH-37PH9UK. I call these jaggies because it’s a sort of blocky jaggedness, rather than a comb-like look as is usual from interlacing. I get the same jaggies from a real-time down-convert on the Kona LHe and from a down-convert to MPEG-2 through Compressor. My SD monitor is a Sony PVM 1220. It’s ancient, but in good shape and properly calibrated. I suspect it’s just the nature of 59.94p. What I’d like to try is to convert it to 29.97p, but I have not found a way to do that by dropping frames from the original 59.94p source. Not sure how or if this relates to your situation, but here it is FWIW!
