Agreed over the few options - but I just wanted to show a simple 
example, to help to get started (the documentation of mencoder is not 
crystal clear about all these options, personnaly I feel somewhat 
confuse...).

Anyway, here is a more complete command I used (note the vbitrate option 
btw, so I guess it exists ;-) )

C:\Documents and 
Settings\Thibaut\Bureau\Videotools\MPlayer-1.0rc2>mencoder mf:
//*.png -ovc lavc -lavcopts 
vcodec=mpeg4:vbitrate=4000000:vpass=2:mbd=2:keyint=1
32:v4mv:vqmin=3:lumi_mask=0.07:dark_mask=0.2:mpeg_quant:scplx_mask=0.1:tcplx_mas
k=0.1:naq -mf fps=25 -nosound -o trybest.avi
