OK. What you are aiming for is close to what I do today,
except I don't do live streaming. I take care to zoom in
quite close, keeping the low target resolution in mind.
I have only used the camera's own microphone so far. Using
a radio mic, and only that, loses as much as it gains: You can't
hear the audience well. I hope we can get a good sound mix, and
I am willing to purchase some hardware for that, if need be.

I don't think "next slide" will fly. But the camera operator could
possibly keep track of it on a timeline, so cues could be added in post-
production.
