Thanks for posting the question, Sam! If you felt that way after watching the video, I'm sure several other people did too.
I can do this slower, but tomorrow I'm off to a wedding on the other side of the country. When I get back, I'll try to make a supplementary video in which I'll show some things in slow motion.
In the meantime, here are a few tips.
First, don't forget that the main point of this video was merely to teach slides and to
introduce the idea that you can slide into a roll. If you caught the big picture, that's great! That's enough for now. I wasn't expecting you to dissect and comprehend every little thing I did with my fingers yet. These concepts and techniques took a long time to sink into my head, so if you're new to these concepts, I'd be amazed if they were crystal clear to you at this point.
Second, if possible, try to watch videos 1-3 a few times because I break things down more in those videos.
Lastly --if you cannot rest until you understand all things in this video-- remember that a regular long roll always consists of a parent note that is divided into three by a cut and a strike. With that in mind, try to notice what finger I'm cutting with and what finger I'm striking with. While it's common to start a roll by tonguing, in this video I demonstrated how you can slide into rolls also. And, as I watch the video myself, I see that I started some of the rolls with a cut at the
beginning of the roll, and then I completed the roll with another cut followed by a strike. I'm sure that this paragraph makes perfect sense to everyone!
Little by little, you'll go a long way.
