Watching the video however, all you see is two statues! Movements were so economical that you might think we never even twitched a muscle, let alone operated controls and switches (but we did). In a heightened state you can draw your colleagues attention to an instrument with the tiniest nod of the head or flick of the eye, and in the real world that is how it works. As a record of the incident, the video was therefore completely useless.
How large were the crew in the frame?
I'd suggest then that there needs to be a camera that reveals facial expressions on each crew member.
This could be used to track (roughly) where they are looking.
One camera for each crew member and a third wideshot to show their arm movements.
View of engines, cargo hold and control surfaces is more useful!
