The question: how to help your boss feel at-ease in front of the camera, when they say: "I'm terrible at this!"
The answer:
"Being on camera is like riding a bike. You were terrible at riding a bike until you practiced and practiced. Smiling puts you at ease, so try to smile well before you hit record. And if you mess up, it’s okay! Keep going...especially in Lives people grant some grace for mess-ups. Also, don’t underestimate the power of positivity: if you use words like success, achievement, goal, outstanding, etc., you are helping your brain to associate filming with confidence and winning. Finally, keep your hands where the audience can see them. As humans, we associate better with other humans when we can see their hands because we know we are not being manipulated or deceived."
