Audio compression artifacts in pre-rendered cutscenes

Does anyone know what is going on with pre-rendered video exhibiting severe audio compression artifacts?

I believe every UE5 game I’ve played in the past few years has shown this problem.

Listen to this clip from Tempest Rising which just released:

Its most noticeable near the beginning and end of the clip, but its constant throughout all the pre-rendered cutscenes. Mechwarrior was just as bad if not worse which really sucked because so much of that story was told through bink files. Even Abiotic Factor’s short startup video is horribly compressed.

Is it something related to the default output settings for these video files and most devs just dont listen that closely to what they’re putting out there?

Thanks

I just realized I’ve been playing South of Midnight and it does NOT have this issue with .bk2 playback, perfectly clean audio, so it can be worked around!
