<suxendrol> okay. well, with two pass we have the original stats file, and then the scaled stats file.
<suxendrol> xvid currrently has no internal scaling routine.
<suxendrol> a) run 2pass1, and generate the stats file.
<suxendrol> b) scale the length field in the stats file using an external tool, such that the sum of all lengths equals the desired file size
<suxendrol> c) run 2pass2 with the first and scaled stats files.

btw, i was thinking that the scaling program could add a 'scaled-length'
field to each line of the stats file, rather than writing out a
seperate scaled stats file. any opinions? 

i belive there is a lot of confusion as to why we need multiple stats
files.
