I can report some progress on this front: upon checking the yuvkineco code for this error message, I discovered that the .dv file being generated by dvgrab is created (or at least flagged as) bottom field first, which yuvkineco apparently can't deal with. Nothing that a bit of fiddling with yuvcorrect can't work around, though. So, I modify the test chain from section 3.4.3 of the HOWTO as follows: smil2yuv -f 40 test.dv | \ yuvcorrect -T LINE_SWITCH -T INTERLACED_TOP_FIRST | \ yuvkineco -F 1 | \ y4mtoppm | pnmsplit - pnm/image%.pnm and out the other end, I get 31 non-interlaced frames (out of the original 40 from smil2yuv), which all appear to be paired up properly. It even seems to properly catch cases where the cycle changes, as seems to happen consistently around scene changes. So, does this mean that I am in fact seeing 3:2 pulldown? If so, I assume I'll have to be careful when editing out commercials in Kino, to make sure I stay on the cycle -- or can yuvkineco detect and correct for cycle changes introduced upstream in that fashion? For conversion to NTSC SVCD MPEG2, I assume I'll need to use the -F 4 setting for yuvkineco, which will presumably duplicate frames as necessary. TIA as always; I'll get this nailed down yet, I will... -sbigham ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users
