[MPlayer-users] mencoder *-vf* isn't a valid option?

I get "vf is not an MEncoder option" when I try using it like the recently
suggested :

mencoder old-big-file.avi -vf denoise3d,scale=480:320 -oac mp3lame
-lameopts q=4:mode=1 -ovc lavc -lavcopts vhq:v4mv:trell:vqscale=3 -o
new-small-file.avi

I've seen this option in the online documentation too, but don't find it
in the man page.  -vop seems to work for me though...  is it equivalent?
