[MEncoder-users] Trouble when making a movie from *.png files

[Mario Valle]

You should use codec msmpeg4v2
or install a mpeg4 codec like divx or ffdshow.
I normally work with this line (from a windows script)

set file_out=x2.avi
set fps=24
set obr=1200
set opt="mbd=2:keyint=132:cmp=2:subcmp=2:dia=2:mv0:last_pred=3"
set codec="msmpeg4v2"

mencoder -ovc lavc -lavcopts vcodec=%codec%:vbitrate=%obr%:vpass=1:%opt%:turbo -nosound 
-mf fps=%fps%:type=png   -o NUL: mf://*.png
mencoder -ovc lavc -lavcopts vcodec=%codec%:vbitrate=%obr%:vpass=2:%opt% -nosound -mf 
fps=%fps%:type=png -o %file_out% mf://*.png

Hope it helps
