Was anyone able to decrypt the usm files in ps4_movieR.cpk?

vgmtoolbox only seems to export blank or corrupted files. I've tried using the 'CRID USM extractor' but obviously that needs a proper key.

Was anyone able to successfully find the correct key? I can see on the wiki someone was able to get the proper titles for the files (see: https://amicitia.miraheze.org/wiki/Pers ... movieR.cpk ) so at least that much progress was made.

Any help would be appreciated.

I can provide a sample file if you can help, I realize the files arent easy to come by.

Thanks

i've been trying to extract some of the FMVs from PS4 releases, as expected, i tried VGMtoolbox, and it spitted some gibberish out, then i tried this method
crid_mod.exe -b 000000000 -a 01C87822 -v -x -i .\mov050.usm
like so, it demuxed it, so i tried to remux it to mp4 or mkv with ffmpeg, but it would spit out a bunch of errors as well, so i tried MKVtollsnix, and while it remuxed the file sucessfully, it was just a corrupted green video file,

did i miss something, or not

*edit: nvm, my key was wrong
