You can also see what it looks like from the control room on Hamish Hamilton's YouTube channel, with the AD calling out shots and all: https://m.youtube.com/watch?v=gfjWjkTP4p8. (Hamish Hamilton has directed every Super Bowl halftime show since 2010.)
John DeMarsico directs the SNY broadcasts for the NY Mets and sometimes posts behind the scenes for how all the cameras come together into a production. I think they are pretty interesting to watch.
