[MEncoder-users] filesize become very big after convertion

[Achilles Xu]

Hello mencoder-users,

I use the following command to convert some video to flv file format.
		mencoder aaa.mov -o aaa.flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts 				vcodec=flv:vbitrate=16000:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -lavfopts 				i_certify_that_my_video_stream_does_not_use_b_frames
The 16000 vbitrate is for get best quality, but the filesize become twice or three times.
What can I do to decrease the filesize without losing quality?
