Hi -
Can the scaling (with "-vop scale=") increase the size? I have a 16:9
DVD (NTSC with 720x480 data) that I tried converted to Divx4 using the
command:
mencoder -dvd 1 -vop scale=854:480 -sws 2 -ovc lavc \
-lavcopts vcodec=mpeg4:vhq -o title1.avi
the movie playback window is the right size but the movie is corrupted,
slanted to the right, with diagnonal lines, and so on. The '854'
is what MPlayer scales to when playing the DVD
If I maintain the 16:9 aspect ratio with the command:
mencoder -dvd 1 -vop scale=720:405 -sws 2 -ovc lavc \
-lavcopts vcodec=mpeg4:vhq -o title1.avi
then the avi file plays back correctly. The problem would seem to
be scaling the width to a larger value (from 720 to 854).
Did I try to encode the widescreen movie incorrectly? Or is there
another manual (in addition to encoding.html and mencoder.1) I need
to read?
Thanks.
