Nice! I dig the music and the overview. The only suggestion I would make is to focus more on giving enough information to really achieve a successful first beer, and leave out the stuff that gets more complicated. For example...
Specify say 1.25qts/lb of grain for the mash temp. Don't worry about letting people know you might need more than a 60 minute boil. Specify a sparge temp and state a certain volume. Maybe do everything based on a certain weight of grains, maybe 8lbs or 10lbs. Get all the "it depends" out of it and just create a rigid framework. With that done, you could actually walk a newbie through an entire first time brewing AG session in less than 5 minutes.
I dig the music too.
I had actually thought of doing something similar. 5 minutes to a successful first AG batch. Then do a video with a little added flexibility... Do a second batch. Then a little more flexibility and a bit more equipment and do a third batch. After about 5 or 10 batches, you could walk a newbie through a ton of little lessons that would have them drinking their way to a rather high level of brewing knowledge... And they could spend more time brewing and less time reading. It'd be a great intro to the hobby.
Of course, I would start with BIAB just for the utmost in simplicity.
