I agree with Phill. Also, looks like 25s on there which means technially you're pulling from a deficit. Once you get to 45s, the pull will be different.
Judging by that video, I'd say your knees are too far forward and you need to stick your ass out a little further so that you use the hips and glutes to lift more than squatting it up. Form looks good, but like Phill said, gotta have more of an effort to really see where your form will break down.
