It's just that when I play from the DVD, mplayer outputs "demux_mpg:
24fps progressive NTSC content detected, switching framerate" but it
doesn't say that when I play back the AVI I made with -ovc copy.  So I
assumed it ditched those flags when it got put into an AVI.  Maybe not.

I wasn't quite sure how best to do this.  Without specifying -ofps,
mencoder duplicates every 4th frame because the AVI is supposed to be
29.97.  The result is that without -ofps 23.976, IAS_clip_dvd.avi would
have been jerky.

Now, when I run filmdint on the jerky version of IAS_clip_dvd.avi, the
output looks fine, because then it removes every 5th frame that mencoder
added.

When I take the clip from the DVD with -ovc copy -ofps 23.976 and
transcode using pullup/filmdint from that, I get the same results as
transcoding directly from the DVD.

We must be looking at different files.  Did you transcode with -vf
filmdint yourself, or look at the IAS_clip_filmdint.avi file I uploaded?
The file I uploaded clearly has missing frames (the first 60 frames
seems to be missing about 3 frames), causing the panning to look jerky.
(Though it's not quite as chaotic as pullup.)

Sorry, that was a typo.  I meant filmdint.

Not sure about that.  filmdint looks broken too, just not as much.

Cheers,
