I'm going to use cls-ue4d by Shegorat, but XTool unreal plugin should also do the decryption.

So, ue4 decrypt with key

Then add zlib precompressor, srep and lolz.

Devs were nasty and put videos inside the pak with compression and encryption. Sounds are also encrypted but you should just be able to patch the encrypted data out using QuickBMS + Unreal script to print a filelist which will give you the locations of the different sound banks.
