[MEncoder-users] Understanding how to increase the size of subs

[David H. Trang]

I have a mkv file and I do a -sid 0 to use the sub, but the sub is very
small I use this command:

./mencoder ~/Movies/5_Centimeters_Per_Second.mkv -oac mp3lame -ovc xvid
-xvidencopts pass=2:bitrate=800 -alang jpn -sid 0 -subfont-text-scale 10 -v
-o 5movie.avi

Why do the size of the sub not increase?

get_path('font/font.desc') -> '/Users/Hong/.mplayer/font/font.desc'
