Auto switch timer/programmable (Timed automatic director)
Timed switching between cameras (or scenes) is useful in the live broadcast of solo performances in which you have your hands busy (for example when playing a musical instrument, or cooking, or doing manual labor).
it is useful to give movement to the scene, changing the shooting perspectives.
Just insert a timer function to the existing function with the hot keys.
like Advanced-scene-switcher-plugin on OBS or in Roland hardware switcher like VR1-HD.
