I tried several fieldmatch variations such as:

ffmpeg -i long.sample.vob -vf
-pix_fmt yuv420p -c:v libx264 -preset slower -tune film -crf 18 -x264opts
keyint=40:bitrate=2100:qpmin=8:qpmax=38:qpstep=4 long.sample.m4v

But just changing the frame rate seemed to have as much success:

ffmpeg -i long.sample.vob -vf fps=24001/1001 -c:v libx264 -preset veryfast
-level 41 -tune film -crf 22 -c:a libfdk_aac long.sample.m4v

What didn’t work very well was the filtergraph without “fps=60001/1001” at
the beginning:

-vf “fieldmatch,yadif=deint=interlaced,decimate,fps=24000/1001”
