How to extract genshin impact cutscenes

[Dex]

I tried to extract the .usm files in StreamingAssets\VideoAssets by using vgmtoolbox, but none of the extracted .m2v and .hca files are playable.These files seem to be encrypted and there are some .auth files which totally don't know what to do with.
I just want the original video without the subtitle and uid watermark.
I've uploaded one of the usm+auth files.Any help is very appreciated.

they are encrypted indeed.
they are decrypted when the game is running, but it's such a hassle to find decryption key and method.

OK, so, update:
You can convert the HCA to WAV and they will play. They are not encrypted audio files.

However, the M2V is a different story and I'm still working on it.

Any updates on this Eleiyas? I tried sending you a private message about something else Genshin related, but it's been stuck on my outbox for the longest time. lol

Now the HCA file has also been encrypted as a bin file and cannot be converted.Do you have any method, please?
