I have recorded a couple of videos, and I just found out that the audio of my game is wayyyy higher then I want it to be, and now it's pretty much the only thing you can hear and you can't really hear my own voice anymore.
Alright, then I'll have to give post commentary. I'm alright with it, its about 2 hours worth of recording, but it's my own mistake. I just heard from someone that their would be a way to split the 2 audio sources, but it seems like that hope is gone now. Thank you for the answer.
