Question about possiblity of merging "Metro Exodus" patch files into main files

[Masquerade]

Why merge them? A lot of the files will be removed when srep runs (since similarity with the original files).

Only big files such as videos you can rip from the original archives and keep the new ones from the patch (since the original ones will be never used).

I assumed srep wouldn't be able to do anything with the modified files as I assumed srep can only work with identical duplicates, looks like I'll have to start reading some theory literature! I'll have a look for any video files though!

It Seems i finally can have a student...

This time of the year i am busy with these projects

1) drastically reduce wem quality for good on titles (100% success so far)

2) drastically reduce overall quality of game rippable files, completely delete old unused files which as you said correctly srep cannot dedup. (70% done almost there)

3) Rip movie files and lower quality then import them back on (100% done)

so far i have managed the following without ever compromising visuals or sound

Packed
Immortal Fenyx Rising > 13.8GB
Divinity - Original Sin > 7.4 GB
Divinity - Original Sin II > ~ 13 GB it's almost complete
Onimusha - Warlords > 2.0 GB
Mega Man X - Legacy Collection > 1.75 GB
Mega Man Zero - ZX Legacy Collection > 1.9GB
Call of Cthulhu > 7.4 GB
Resident Evil 2 > 13.8 GB
Resident Evil 3 > 13.6 GB
Those 2 can be done together with astonishing ratio 30% or more
Resident Evil HD > 3.8GB
Resident Evil Zero > 5GB

These projects sound fascinating! I remember seeing .wem files when attempting to encode video/audio for "Batman: Arkham City" but unfortunately had little luck with this.

How drastically is the the sample rate and bit depth of each track reduced to see results? I don't know anything about audio compression, sorry if thats a silly question.

Do you have a specific method to determining which files are unused in a title, or is this a case-by-case or engine specific method? I attempted to figure out which files were unused in the title "Silent Storm: Sentinels" as it uses a fair amount of files from the title "Silent Storm", but I was unable to figure out which, if any, could be removed.

Sorry if I sound silly but what exactly do you mean by movie files? I wasn't aware video files could have lossless compression applied to them, with significant compression ratios. It'll be interesting if this project could be applied to the Batman Arkham City, Origins & Knight titles, as the video files in these titles takes up a good portion of the install size.

Your current listed lossless compressions are incredible to say the least! I'm especially amazed by your ratios with the Divinity Original Sin games as well as the Mega Man collections!

No, the files do not have to be completely identical...

@panker1992 please message me those videos too (that's if you planned to send them privately in the first place). I do not want to miss out on what you've been working on.

I have made a Thread on how to do it with video, videos are public you can check them on the forum


ffmpeg.exe -i "input.webm" -c:v libvpx-vp9 -b:v 2000k -c:a copy -c:s copy -y "output.webm"
all files from Total War Remaster from 3.7GB of videos down to 1GB> Total Repack Size = 14.8GB
