Here's a saying

LOW TECH WILL BEAT HIGH TECH EVERY TIME.

In this situation it means no amount of technology will improve the "low-tech" aspects of this person's golf swing. Why on earth this would even need to analyse his swing frame by frame is beyond me, it's obviously unsound from his grip to his footwork to his back swing, his bent arms, his position at the top. And the instructor seems to be concentrating on his open club face at impact. I think there are MANY places you could help this poor chap without needing to video his swing.
