So I have had Vegas Pro 15 for 1-2 months since it has been out, and any downloaded video I put in it is fine audio, but... Whenever I put a video I recorded with Win 10 Game Bar in Vegas Pro 15, it makes the audio very distorted! Here is a video from someone that shows you what I mean and how they fixed the problem for them:
I don't want to fix the problem with a tool, I just want it fixed without any conversion program!
If your video is AVC, try disabling so4compoundplug.dll: https://www.vegascreativesoftware.info/us/forum/new-avc-issues-in-vp15-try-disabling-so4compoundplug-dll--108345/
It isnt avc, its mp4
AVC is video stream format. MP4 is a container. MP4 can contain AVC, as can other containers such as MOV etc..
