Yeah, I figure he's using a differant compiler and/or options.
The significant point is that the results are differant as well.
As a first take, I diff'd the .pass files for my 7800 frame clip. These were both "full quality" first passes (not using the fast approx routines).
There are no differences in I frames (interval 240), scattered differences in isolated b-frames, and two segments with runs of differant p and b frames - one 198 frames long, the other 210 frames long. For example: ( <! is Koepi, !> is mine )
Code:
<! b 3 0 2560 0 4104 2879
!> b 3 0 2560 0 4106 2900
<! b 3 0 2560 0 5498 4357
!> b 3 0 2560 0 5471 4337

fwiw, output files
Koepi 118,568,960 bytes
mine 118,566,912 bytes
Does this provide any clues as to what / where / why they are differant?
How do you determine which one is "correct"?
