First off, all of these reps are high. Probably. READ THE STICKY on filming form checks posted JUST FOR YOU at the top of this forum.
Second - you stop driving your hips up as soon as you come about 1/4 of the way up, and you lift your chest. Stay in your hips all the way to the top.
Finally, I think your stance might be a little narrow - your feet are rolling outward (supinating). Take a slightly wider stance, and see if that helps.
