[MEncoder-users] scaling

[Uzu Maki]

length of movie = 1H20

mplayer says: 720x576 => 1024x576

my encoding options:
-oac mp3lame -lameopts abr:br=128
-ovc xvid -xvidencopts bitrate=1500:pass=1
-vf crop=704:432:7:72,scale=700:302,pp=lb

and when reading movie.avi -> 700x302 = perfect
(500Mo)

QUESTION:
this is hardly a question...
I've started doing this when I got bad resulting files when murging (MKV, OGM)
(this = checking out the output scaling of mplayer {1024x576 in this example}
and using what I think would be better scaling in my encoding options...)

I don't understand really what happens...
Is there anything wrong in my way of mencoding ?

Thanx for any enlightenment...
