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

 <! b 3 0 2560 0 15629 7732
 !> b 3 0 2560 0 15652 7742

 <! b 3 0 2560 0 13280 6691
 !> b 3 0 2560 0 13280 6690

 <! b 3 0 2560 0 7909 5051
 !> b 3 0 2560 0 7907 5048

 <! b 3 0 2560 0 10205 5730
 !> b 3 0 2560 0 10211 5734

 <! b 3 0 2560 0 11031 5689
 !> b 3 0 2560 0 11034 5682

 <! b 3 0 2560 0 4950 2688
 !> b 3 0 2560 0 4947 2688

 <! b 3 0 2560 0 3489 2439
 !> b 3 0 2560 0 3495 2437
and
Code:
 <! p 2 47 2505 8 17747 5163
 !> p 2 46 2506 8 17743 5161
 <! b 3 0 2560 0 4003 2819
 !> b 3 0 2560 0 3999 2814
 <! p 2 48 2503 9 17272 5148

 <! b 3 0 2560 0 3695 2587
 !> b 3 0 2560 0 3705 2596
 <! p 2 47 2512 1 17926 5131
 !> p 2 47 2512 1 17929 5132
 <! b 3 0 2560 0 3206 2219

 <! p 2 45 2511 4 17892 4939

 <! b 3 0 2560 0 4197 2658

 <! b 3 0 2560 0 3496 2529
 !> b 3 0 2560 0 3493 2529
 <! p 2 68 2484 8 17503 4963
 !> p 2 68 2484 8 17502 4963
 <! b 3 0 2560 0 3120 2309
 !> b 3 0 2560 0 3113 2298
 <! p 2 70 2480 10 18055 4899
 !> p 2 70 2480 10 18068 4894
(continues)
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"?
