Using the tool, decompress basegame_5_video.archive located at:
This contains videos for menus, effects, in-game adverts and more.
Once extracted, they can be viewed via RADTools as Bink Videos and converted to other formats.
Use ww2ogg to convert decompressed archive audio to .ogg through command line, as well as Revorb to get smaller and cleaner files that can be played via other media players such as VLC. ffmpeg can be used for more convenient playback.
To execute conversion:
.\ww2ogg.exe "<!AudioFilePath!>.wem" --pcb packed_codebooks_aoTuV_603.bin
The argument --pcb is important so as not to return gibberish audio files.
It is also recommended to turn down the volume upon playback.
