First thing, the video is at an angle that makes it hard to see depth so I can't comment on that. The things that I notice are all on the way up. When you first start to drive up, your back rounds - that's likely because you aren't actively trying to maintain a flat back. I mean, I'm sure you are, but it's not sufficient at this weight. In addition, as you do this, your center of mass shifts slightly forward, resulting in you bending too far forward. It's not the worst I've seen, but it's significant and I imagine it does affect your efficiency and drive.
Tips: push your butt back and try to maintain a neutral spine as your drive up with weight more on the heels than the toes. Try it out at lighter weights, see how it feels, and then begin incorporating the new form at your work weights.
