Q: two-pass quality encoding

Hi there,

I dont use the two-pass encoding, because AFAIK it tries to keep the
bitrate fluent - which I dont care about. What I care about is
quality, that's why I use fixed quantizer value.
But there is the problem - I have to encode the source twice, trice or
even more till I get the right number to fit the output file to e.g.
700MB. Is there a way how to get this without trying numbers and
reencoding? (If the encode takes 30 hours as the video I encode right
now, it is a real burden)
