[MEncoder-users] NTSC DVD ripping - inverse telecine artifacts

Hello,

I bought some DVDs of my favorite anime but I experience problems encoding
them.

It is an NTSC Mixed progressive and telecine video (mplayer switches back
and forth between "30000/1001 fps NTSC" and "24000/1001 fps").
I used the 'pullup' filter associated with 'softskip', which produce these
results with a few frames:

Here is the telecined frame that causes problems:

I downloaded the same episode from a torrent to compare the quality. The
encoder did a great job and got this result:

I don't think this encoder used the same source as mine, but I'd like to get
some advice from experienced encoders to help me fix my problem and get a
similar quality.

The command line I used:
mencoder dvd://1 -nosound -ovc x264 -x264encopts
bitrate=1200:subq=4:partitions=all:me=umh:frameref=3:bframes=2:trellis=2:b_pyramid:weight_b:threads=auto
-ofps 24000/1001 -vf pullup,softskip,scale=640:480 -fps 29.97 -o Output.avi


Thanks a lot!


Regards
