Very interesting and it helps to understand the different videosystems out there for drone racing and freestyle. There is a trend towards digital videosystems right now which i now understand better, so thank you.

Wonderful video, however, I learned this in Engineering school in college, it may have been tough to do in middle school :)

I thought you all were switching only to a grade school emphasis. However, if it will help me in medical school, please keep it coming!

I am so confused about the binary bit. How does 11000 equate to 16, 8, 4, 2, 1??

Why do you call this "Middle school physics." I'm 19 and want to learn about this now.

Sure middle schoolers should be taught this, but learning is for all ages.
