I have a live production with 3 PTZOptics NDI cameras and 2 vMix Pro installations. For some of my broadcasts, I want to make some of my broadcasts simple and easy to use for inexperienced users. I have mostly been able to do that with scripting and hotkeys. However, I would like to highlight, hide or make unavailable certain inputs. For instance, If I have hotkeys set up to change camera inputs, I would like to be able to lock out other inputs for the same camera to prevent sending viewers for a ride if my "Rookie" presses a hotkey for a different input for the same camera. Locking out is likely not an option, but I was thinking that something like this "may' be done using activators and hardware like Stream Deck. Another words, if a particular key was highlighted when pressed, could I also highlight other keys associated with the same camera to provide a visual that those inputs were off limits?
