Comment (by navilor):

 This is the command line I just ran to replicate the problem.

 {{{
 ./zffmpeg.exe -v 9 -loglevel 99 -i S01E01-small.vob -sn -dn -vf
 yadif,decimate,dejudder,crop=720:480:0:0,scale=720:480 -pix_fmt yuv420p

 -map_metadata -1 -f mp4 -y f:zcygout/S01E01-decimate.mp4 &> 7055.log
 }}}

 I have just uploaded a zip file called Ticket 7055-001.zip that contains
 all of the following:

 1) S01E01-small.vob which is the source file.

 2) S01E01-decimate.mp4 which is the output file.

 3) The console out log file called 7055.log.

 4) The ffmpeg2pass-0.log file.

 5) The ffmpeg2pass-0.log.mbtree file.
