Can you post ONE video (series) which made a difference in your game?

Now, that I am committed to a private lessons that involve drilling 1000's of balls to develop muscle memory on various aspects of the game, I feel I can better appreciate watching some videos.

There is an overflow of media out there, and I don't have time or interest to watch 100's of hours of videos. Can you post ONE video which made a difference in your game?

I want to watch some videos now that I have a better understanding of the technical aspects of tennis, and maybe I can get some ideas and start to incorporate. But the only way I will truly learn and incorporate anything new is with hours and hours of ball feeds. I am 1000% bought into the idea that private coaching is the only way to evolve your mechanics. Note, I did not say get better. Yes, you can play a lot of USTA and optimize your mediocre game and make fewer unforced errors and whatnot and totally win matches. But, you will never have the mechanics and footwork of a 4.5 or 5.0, for example without private life coaching.
