you don't manual with your arms, you push with your legs.
you need to throw your weight back a bit to get the front end up but you're not pulling the bars up to your crotch. pull up by throwing your weight back and push forward with your legs by straightening them - that'll bring your bum and weight back and straighten your arms at the same time so you're all off the back of the bike
video looks like you're going the right way though
Finding it tricky to control the front rising, as it comes up I move forwards and have my groin against the stem, but it's still looping out - I can't get any further forward so I'm at a bit of a loss as to how to tackle this.
