You can also add (“+”) and remove (“-“) “Scenes”. Scenes are presets sources than you can mix together. Later, you can also assign hotkeys to switch between the multiple Scenes you’d have created. To do so, go to the “Hotkeys” tag of OBS’s “Preferences”.

Before starting the stream, make sure all the following settings match the picture below.
Keyframe interval = 2 seconds and nothing else , rate control = CBR, profile = baseline.
