>From what I can tell, libx264 embeds its encoder settings into the
resulting movie, whether employed from mencoder or from ffmpeg. As
discussed here:


those settings aren't exposed by any programs other than mediainfo, but
you can also see that embedded info doing something like this:

$ strings < out.avi | grep -E "x264.*core"

You should at least compare the settings from mencoder and ffmpeg (and
share the output here), as you/we might get an indicator as to which
setting is leading to bad results.

I also haven't seen the full uncut console output of either encoding command
yet, please do provide. Just in case. :-)
