I always wonder if all the orchestra was given a click and a copy of the modified video, if the conductor could just sit down and eat a sandwich.
Got to try a rehearsal like this with my high school band (Sorcerer's Apprentice, IIRC). There was still enough other information to get from the director (adjusting dynamics, etc.) that we probably would have sounded bad with just the video.
they often consider this sort of conducting much harder despite these added tools
I'm not sure it's an added tool so much as a more exacting spec.
