method
converted all bk2 to bik with a bk2 file extension so the game recognizes it
and to avoid bpk compression errors bitrate is the same so the video is lossless due to that

on main game files
bpk on bk2 files
original size 44gb
repack size 29.gb

I know this is old but... I took a look on this and was surprised that you have precompressed this game with such a method.

I used the same as you did and after 3 hours I was into 30%... still precompression stage of course.

I know this game is old and no ass will repack this ever anymore but whatever.

So I looked up the game files and came to the following conclusion:
The game is shipped with oo2core_6_win64.dll which is v2.6.0 but some of the game files were compressed with a different oodle version, namely v2.5.3. You cannot precompress some of the files with shipped library. You will get 0 streams precompressed, plus it takes a long time.
So I wrote a quick xtool plugin.
I think all the files are compressed with kraken level6 (I am not in the mood to look up over 20k files, so I assume all the files are compressed with kraken level6).


Some examples.

-mwwe2k19
Streams: 809 / 809
Time: 00:00:26 (CPU 00:02:24)

Size: 353 MB >> 0,99 GB

Done!!!

-mkraken:l6
Streams: 498 / 802
Time: 00:01:33 (CPU 00:08:07)

Size: 353 MB >> 921 MB

Done!!!

-mkraken
Compressed 109 files, 1,866,438,656 => 3,240,060,056 bytes. Ratio 173.60%
Compression time: cpu 1.50 sec/real 327.79 sec = 0%. Speed 5.69 mB/s
All OK

-mwwe2k19
Compressed 109 files, 1,866,438,656 => 3,327,328,916 bytes. Ratio 178.27%
Compression time: cpu 1.69 sec/real 166.69 sec = 1%. Speed 11.20 mB/s
All OK

I said that some of the files are packed with a different oodle version, namely v2.5.3.
So you have to use two libraries at once to get probably all the streams.

Example:

xtool:mwwe2k19:oodleoo2core_5_win64.dll:core_2.5.3+xtool:mwwe2k19:oodleoo2core_6_win64.dll:core_2.6.0

Compressed 1 file, 746,374,144 => 4,560,712,728 bytes. Ratio 611.05%
Compression time: cpu 0.88 sec/real 96.40 sec = 1%. Speed 7.74 mB/s
All OK

xtool:mkraken:oodleoo2core_5_win64.dll:core_2.5.3+xtool:mkraken:oodleoo2core_6_win64.dll:core_2.6.0

Compressed 1 file, 746,374,144 => 3,790,919,089 bytes. Ratio 507.91%
Compression time: cpu 1.05 sec/real 296.24 sec = 0%. Speed 2.52 mB/s
All OK

I did not tested this with the full game. If anyone wants to dig deeper then there you go.

Edit: I guess it's better to first use the higher library, then the lower (2.6.0 -> 2.5.3).

[Stream1]

-mxtool:zstd:l11+gdeflate (libzstd.dll v1.44).
Needed Xtool 0.9.5

What is the best compression method for .unity3d files ? Does it vary from game to game ?
