Question

Video

How to record video from the game so that the sound is recorded only from the game, and not from the voice chat (not the game chat).
Somehow to direct sound recording only from a certain process. What software will allow you to do this?
I write the video through the radion software, there is no such possibility (as far as I know).

Set up a virtual mixer (I, for example, use voicemeeter), redirect input channels to separate outputs, put one output in Windows, where you have both the discord and the game and all the persimmons, and output only what you will write to the other, and grab it obs'om, or whatever you write there.
