So it works with 64-bit but doesn't with 32-bit.
That's really strange.


I need those rips for an Apple environment.
VC-1 won't natively work with Apple. So I need to re-encode.

I have some final questions:

Code:
x264-r2935-545de2f.exe --bitrate 16998 --preset veryslow --tune film --bluray-compat --vbv-maxrate 40000 --vbv-bufsize 30000 --level 4.1 --keyint 24 --open-gop --slices 4 --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --sar 1:1 --pass 1 -o out.mkv OLD_BOY.Title0.mkv

x264-r2935-545de2f.exe --bitrate 16998 --preset veryslow --tune film --bluray-compat --vbv-maxrate 40000 --vbv-bufsize 30000 --level 4.1 --keyint 24 --open-gop --slices 4 --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --sar 1:1 --pass 2 -o out2.mkv OLD_BOY.Title0.mkv
- How does these commands alter my source. I mean, would there be less alteration when I do something like this (and would that bring me closer to the source? Do I need to worry about BluRay compliance, when the source is a BluRay?):

Code:
x264-r2935-545de2f.exe --bitrate 16998 --preset veryslow -o out.mkv OLD_BOY.Title0.mkv

- Why does x264 show the following during encoding:

Code:
lavf [info]: 1920x1080p 1:1 @ 24000/1001 fps (vfr)
--> vfr

Is it that problem:

Mkv will store it so the frame durations switch between 41ms and 42ms so that on average it is 41.7083....ms. Technically it is vfr, but for practical purposes it is cfr (as was the original source).

If you are unsure just leave the fps settings alone.
And would it be better to use --fps 24000/1001 (implies --force-cfr?)?
