Given that the video is Photography 101 level, I'm not sure that taking guidance from what professionals do is necessarily the best idea. Maybe fumbling around trying to control everything manually gives you slightly worse photos initially, but a better understanding of light and photography as you go along. Just like if you just got a Raspberry Pi and you're writing some code to blink the lights on your christmas tree, you may not want to do it like the pros and write unit tests and develop features in branches that get merged by pull requests.
