You can even rip out unused languages from videos files with ffmpeg. Unfortunatelly the audio streams are not named, therefore you have to figure out what audio stream is what language they speak.

Usage:

ffmpeg -i "C_GameEnd.mp4" -map 0:0 -map 0:X -acodec copy -vcodec copy "Processed\C_GameEnd.mp4"


-map 0:X
I don't know what number is for which language. Use MPC and change audio track to listen.

X = Audio stream ID

-map 0:0 is the main audio track (non-voice) I guess.

First -map 0:0 tells ffmpreg to not touch non-voice track (main audio like sounds and stuff)
Second -map 0:X tells ffmpeg to not touch selected voice audio track (X).
In the above example ffmpeg removes all audio tracks with the exception of 0 (main audio track) and X.
"-acodec copy" tells ffmpeg to copy audio source (it doesn't change stuff like bitrate, etc.). Just a 1-to-1 copy without changing anything.
"-vcodec copy" is the same for video source.

If you want to leave 2 voice languages, add a third -map option:
ffmpeg -i "C_GameEnd.mp4" -map 0:0 -map 0:X -map 0:Y -acodec copy -vcodec copy "Processed\C_GameEnd.mp4"

Audio track 1 is english, audio track 3 is German. Can't understand much more right now.

Start Size: 69GB

Compression Method:

• xtool+srep+lolz

Final Size: 20.3GB

Notes: This game does use bink video. I unpacked the bundle files but could not see any videos, not even a videos folder. I didn't take a deep look however.

If you can find the videos, you may be able to patch them out of the bundles then use bpk to lower the size.

I think you forget to add about 990 MB worth of .movie files (from The End achievement) and 2.9GB of soundtrack (flac and mp3), so the final size should be around 73GB.

Edit: I own the game and it is 73GB, so I just think that 69GB is just the bundle files with the dlls and exe :P

unless you have to play throughout?

Kingdom Hearts HD 1.5 + 2.5 ReMIX
Main files - Xtool(xzlib)+srep+lzma (lolz takes 3 hours longer and there is barely a difference)
Video files - srep+lzma

Starting size: 45.84 GB
Output size: 34.4 GB

- Days/Recoded videos are ripped, since they're just compiled cutscenes turned into two extra movies.

Has anyone looked at the video files yet for the main games? They seem to be MP4s, but it's not possible to view their metadata/bitrate or even play them. I assume there would be no way to remove this encryption, right? Never heard of videos in a game having such a thing before.

They are mp4 files for sure. Looked a bit with hex

But seems to crypted or somewhat, for whatever reason.

Was there ever an LZMA precompressor? I was reading some ancient threads in my search. At the time, it was said to be a difficult task and to avoid large xdeltas the right params had to be used in recompression. Read a bit on Encode through the wayback machine, but nothing really related to what I was looking for.

Reason I am asking, Crash Bandicoot N Sane Trilogy uses LZMA compression on the archives:



There's an Extract tool for this game which removes the compression from the pak, and saves it as an decompressed pak file, only thing is no way to re-compress said pak.

https://github.com/AdventureT/Nst-Ex...r/SevenZip/sdk

Update: https://github.com/pashok6798/Crash-.../master/CBNSTT

I found another tool with compression abilities, however it is a GUI with no command line unfortunately. Its says it can compress but it doesn't appear to do.

Method : xZLib+SREP+LOLZ
Method 2 : SREP+LZMA
Method 3 : SREP+4X4:LZMA
Initial Size : 33.6 GB
Final Size : 26.6 GB
Hints : *.pak - *.usm,*.uasset,*.awb - Other Files

I was trying to decompress DBZ : Kakarot with the methods mentioned above. I was able to extract all the archives except the *.pak ones, which were compressed using xZLib+SREP+LOLZ.

While decompressing, i ran into an error saying :

ISDone.dll
Error code : -12
failed CRC check at pakchunk0-WindowsNoEditor.pak

If someone else faced this issue before or it was discussed in the past please refer me to that thread.

Edit : I managed to decompress the *.pak archive with LIS.

It might be the code itself?

The installer code? maybe, i am going to try some other installer scripts and see if it works.

For this one i used WPI by Razor12911 - added some external compressors and most of the time decompression goes smooth.

Edit : Check above messages.
