It's a "you can't have it both ways" problem (and there must be something in the MJPEG-Howto about this --- I hope). The original source was 24fps, non-interlaced. It was converted to 30fps, interlaced, for an NTSC laserdisc. This was accomplished by duplicating 5/4's of the fields. Now, 1(2?) frame out of 5 has a field from a different source frame; it makes for relatively smooth, simple framerate scaling. The purpose of yuvkineco is to recover the original 24fps non-interlaced stream, by reshuffling the fields. Apparently, it will let you have a 30fps non-interlaced stream, but that requires leaving in the doubled frames. If it's just the interlacing that bugs you, you could run the stream through a deinterlacer (yuvdenoise) instead of yuvkineco. I'm not sure if the results will look much better, though (since the source isn't *really* interlaced (i.e. fields sampled 1/60th second apart)). (And that's pretty much all I know; good luck!) -matt m. >On Fri, 2003-03-14 at 23:54, Matto Marjanovic wrote: >> >I have an NTSC 30fps interlaced laserdisc with some footage which I am >> >told was originally 24fps.
