Data1a -> pak files

Data1b -> all except pak and emov

Data1c -> emov files

This is basically a update for my last report about this game.

English, French and Japanese movies were ripped. Game was tested 100% in german + english with ripped video files (I played the game twice in english + german with all additional side quest stuff + DLC). I assume it will work on french and japanese languages too.

How to know if the game works with ripped movie files? You will encounter game freezes on points were a video should play (the game is not "freezing" actually, but you can't do any actions). Luckily you can guess which video is missing or wrong ripped by folder and file names.

*_US files are used for english only. Files without language code are used by french, german, japanese (except for credits videos, but this is obvious).

You can delete language voiceovers out of "pakchunk0_s23-WindowsNoEditor.pak" file with quickbms + hex editor to save additional ~2GB, but I didn't for this test.

1. Exctract .mp4 from .pak archive (qbms -f *.mp4 ue4_27.bms <path_to_pak-file> <path for extracted files>)
2. zero-byte build .mp4 cmd

3. Reimport your zero-bytes .mp4 to .pak file (qbms -G -w -r -r ue4_27.bms ue4_27.bms <path_to_pak-file> <path for extracted files>)

Hello, just a question when importing 0bit files, if I redo an extraction of mp4 files should I have 0bit files?

Yes you will have null video files.

Zero bytes still takes up space, if you look at them in the file explorer the size doesn't change, since 00 bytes are repeated all until the end of the file, lossless data compression algorithms takes good use of repeated bytes, hence the compressed file is so small.

i think that's how it works :D though i am not sure.

OR

you can take srep for example, it just saves the position of dupes occurrence and copies a single of copy of these dupes to those positions during decompression.

Help with compressing Ender Lillies smaller please. Thanks.

what about the ucas extension? is xzlib taking care of both the .pak and .ucas files? I was only able to compress it to around 870mb.

Yes. In this case, the UCAS files are not encrypted.

Winter Ember [Build 8534177] [Lossy + Lossless]

If you want to recode the videos, you can recode them to 3000kb/s bitrate using ffmpeg:

Code:

for %f in (*.MP4) do ffmpeg -i "%f" -b:v 3000k "_%~nf.MP4"

You can view a comparison between the quality of original videos and recoded videos here.
