mencoder: encoding options for 1st pass

[TheFogger]

Hi,

When I encode my movies with mencoder and libavcodec/mpeg4, I use the same options for the first pass as I do for the second (except vor the vpass option, of course.) Here's what I typically use:

vbitrate=X
vhq
v4mv
precmp=3
cmp=3
subcmp=3
vb_qfactor=1.25
vb_qoffset=0.6
vmax_b_frames=1
qpel
trell

Encoding is a rather lengthy process with these options. Can someone tell me which options are actually necessary on 1st pass? It's just taking so damn long.

Cheers, Fogger

All these options have an effect on what info is written down to "divx2pass.log". Therefore it is propably good to use all these options in both passes.
