[MPlayer-users] cropping & scaling

[andrea_meroni]

Hi!

this is my encoding command:

mencoder -dvd 1 -ovc frameno -o frameno.avi -oac mp3lame -lameopts  preset=128 -alang it  && mencoder -dvd 1 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=949:vhq:vpass=1 -vop scale=716:304,crop=716:432:2:70 -oac copy -o /dev/null && mencoder -dvd 1 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=949:vhq:vpass=2 -vop scale=716:304,crop=716:432:2:70  -oac copy -o they_live.avi


questions:

1. why don't I get the film properly cropped? I mean that after encoding I still see the black bars as in the original dvd (and with the same size)
2. are the scale values correct (is it correct to use the crop-x-value to scale?)? or should I use 640:272? Where is the difference?

thank you all in advance

bye
