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

[Mario Valle]

You know the phrase: "this is left as an exercise to the student..."
Anyway:

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

Ciao
