I'm a little bit confused how resolution is working. If i have 1920x1080 default monitor resolution, I set same in my game, record in fullscreen and then in video editing software i put same resolution and aspect ratio than a video uploaded to youtube is HD 1920.
But what if I want to play on lower resolution in game, and still upload HD 1920 video? How this resolutions are related to each other? I don't get it.
