didn't watch but imo scrap the stationary shit, you can do them stationary if you learn them rolling but if you learn them stationary you will have to re-learn them rolling, even slow as shit, the momentum brings a whole other kind of balance that you should learn and once you get over the fear it be way easier too, using the momentum is part of the overall technique
Just start moving and ollie-ing! Those 2 ollies after :20 were ideal if you were moving. you are "popping" real good and just need to learn to ollie in motion, in order to learn the real body motion required to do a proper ollie.
My money would be on the high probability that you will learn a moving ollie quickly, especially since you got ollies of that quality while stationary, BOSS UP and just go out and ollie some sidewalk cracks, or even push off those walls you're 'practicing*' in and just crack a little slow ollie. Be careful of sliding out and fuckin shit up, I bet mom or that landlord shall be heated if not.
*this is a great time to go out and actually use your skateboard to just ride over shit and have fun with it, making up dumb ass tricks, etc. Chances are, if your skateboarding is "practice" like this, things will get dull/hopeless in times where you aren't progressing as quickly as you hope.
I remember Mike Vallely responding to someone's letter by saying "i've never 'practiced' skateboarding in my entire life, i just go skate."
I definitely think you need to adopt this principle: take yo ass outside and go skate, while placing heavy emphasis on ollieing as much stuff as you can.
From what I've seen your beginner ollie is awesome, I wish I had it when I started attempting to take it to obstacles, you're ready brethren, go rip!!
