Bar placement is in the ballpark, and this is a better camera angle to assess it from, too. Wondering if you could move your grip in by one finger yet have straight wrists, in order to get tighter. Set grip, then duck under the bar and don't wiggle your hands around. Bar could very well be half an inch high still; with the bar in position, you should be able to feel your acromion above it. In short, this is one of those things that is easier to deal with in person.
Your spine is now solid, but seriously consider a 4" belt. Other previous feedback is the same: drive knees out, bend over. Back at the squat teaching progression, notice how folded up you are when your elbows are between your knees. Stance looks wider in this video; go back to your original heel width. Drive hips straight up instead of slightly backwards.
At the completion of the set, bump the bar straight into the uprights, then you know you're over the hooks and can safely lower it.
