Hey Mike
Reference the stickies at the top of the forum for optimal filming guidelines. Higher up and more from a 10 o'clock angle would be best so we can see what's going on with the back.
You take the time to get your shins in place before bending over, then you sit down too low and nudge the bar forward. Once you've got the stance, don't allow your legs to bump it forward when you bring your shins to the bar. Hips will be higher than they are in this video and the shins will have a bit more vertical angle when done correctly.
Move the grip out a finger-width as well.
Hold the knees back longer when bringing the bar down so it doesn't have to travel around your knees to get back in right spot on the ground.
Work on that for a bit and see how it goes.
