Hey all,

Could anybody tell me what is wrong with my command regarding the size of
the generated file?
I need to convert some videos (.wmv, .asm, .avi and .mov) to FLV videos, at
the moment they are uploaded, I am using the following command, but the
generated files are beeing created too much bigger than the original file.

/usr/local/bin/mencoder SOURCE_FILE.wmv -o OUTPUT_FILE.flv -of lavf -oac
mp3lame -lameopts abr:br=56 -vf scale=320:240,harddup -ovc lavc -lavcopts
vcodec=flv:vqscale=14:keyint=8 -srate 22050 -ofps 30
