It's like the same old movie director issues.
There's nothing new here. But a tip. In days of old you were very careful about use of the film. Film costs were far beyond what you have today so don't bother telling them to press stop and record. Just hit record and cut it up in post production.
I've encountered some folk new to this and they were losing hair over the missed shot. It was very easy to solve by pressing record and let it record for the entire set.
