[MEncoder-users] problem making youtube/vimeo quality flvs

[Adrian]

Hi,

I'm trying to rip a DVD and encode it with mencoder but
my results look bad. I have tried increasing the bitrate to
3600 and beyond.  Here's what i'm using:

mencoder -srate 44100 \
 input.avi -vf harddup \
 -o output.flv -of lavf -ovc lavc \
 -oac mp3lame -lameopts abr:br=56 \
 -lavcopts vcodec=flv:vbitrate=900:last_pred=3

Youtube has flv files that look amazing and have relatively
small filesizes for their length,  eg:
http://www.youtube.com/watch?v=hIMfUbRLLuM   (20MB)
http://www.youtube.com/watch?v=jwTJ7mCcFoY   (21MB)

I can't get anywhere near replicating the quality of my source
material (DVD) in the flv output with mencoder.   Can anyone help?

Thanks,
Adrian.
