Can't seem to be able to select the bitrate while doing 2-pass encode with ffdshow's VfW Xvid encoder.

Here is what I see

and only a maximum bitrate option

size = bitrate * lenght of the video (but watch the units)

can't somebody just make it simple by adding an average bitrate option.

also what is the 2nd pass int and 2nd pass ext

From here (http://doom9.free.fr/xvid-vdub.htm)

2 Pass - 2nd pass Int is the internal 2nd pass encoding mechanism. The codec will scale the bitrate curve in accordance with a couple of settings I'm going to explain later.

2 Pass - 2nd pass Ext won't do any scaling but take it from a processed bitrate curve (only GKnot can do that).
