Well, it seem my offer hasn't triggered a torrent of cheerful replies, but
that's OK.

Looking at the vfw front-end, it looks like the options that need to be changed
would be:
Motion search estimation: 6 (Ultra High)
VHQ mode: 1 (mode decision)
Use chroma motion: on
trellis: on
min quants for I, P, B: 1 (instead of 2)
keyframe boost: 10
I'm not too sure for the following options as the value O might have a special
meaning, like "default value".
vbr_kfreduction (=I-frames closer than... (frames) :1 (instead of 0)
vbr_kfthreshold (=... are reduced by (%)) :20 (instead of 0)

Other than that, everything looks the same
