Not converting to MP4 or OGG (Kinda sloved)

[SwagzWasHere]

For some reason, the converter just doesn't convert my bmk file. I put the bmk file in the Game Files folder, and the converter says 0 files found. Why?

Nevermind. It might just be because the material inside the bnk file might not be supported, or just encrypted, or smth

Check if it's bmk or bnk. The first one is clearly not supported.
Try this BNK extractor directly: https://github.com/eXpl0it3r/bnkextr
Seems it's the official one.
As it tells in Usage, execute the exe from the command line in the same folder with your BNK, maybe trying with /swap.
And see if the tool detects the format it expects.

If not, maybe it's not the same BNK the tool supports, or some other version of BNK format.
You could ask it in that project, though it seems an old one.

I would say ask on forum.xentax.com (that's a forum for game files extraction in particular),
but it seems to be off since the end of 2023...
So maybe you find something in its archive: https://reshax.com/files/file/20-xentax-backup-index-wayback-machine/

And it seems that another portal, reshax.com has some posts on game audio processing. Check that too.
