hello ppl!

I'd like to ask your advices in an encoding matter.
I have several files, which I'd like to encode into flv. They're in 
different formats,
but most likely wmv2 and wmv3.

Currently I'm using mplayer:
mencoder original.wmv -vf harddup -ofps 24 -oac mp3lame -ovc lavc 
-lavcopts vcodec=ffv1:vstrict=-2 -o out.avi

then ffmpeg to encode this out.avi into flv:
ffmpeg -y -i out.avi -f flv -b 512 out_end.flv

but the flv's quality really sucks. If I change the bitrate to 1024 or 
2048 or above,
then it's ~fine, but the filesize gets bigger and bigger..

what options could I tweak? I'd like to keep my file's sizes little, but 
I wouldnt like to
loss a lot quality..

Thanks in advance,

Zoltan NAGY,
Software Engineer
