As a courtesy, next time you post a video cut off the first part where nothing is happening. For example, you should trim the first 15 seconds off this video.
You never really get your upper back/chest up. You start rounded and then stay that way. This makes it near-impossible to lean over without the bar rolling up. I can't tell for certain from here whether the bar starts in the right place, but regardless, you've gotta get your chest up and locked that way before you unrack the bar. Think "superman chest" and like you're trying to lift your chest into your chin. Then keep your neck in place, don't stick it out, and gaze stays DOWN the whole rep.
Additionally, you're dropping fairly uncontrolled into the bottom. Control your descent - not slow, just YOU in control the whole time - and drive up from there. Your depth is OK, just get there in a more controlled manner and that should also clean up a couple other things.
