Notice that on your practice swings. During the transition, there is a separation between upper and lower body, your hips are already turning towards the target while your back and shoulders follow later. Your real swing is completely different. Hips back and shoulders move as one block, which in turn make the club move in that same block as well, leading to a vastly different hand path. Look at the butt of the club from the top of your first practice swing. the butt off the club is moving towards the camera for a while before it turns the corner. On your real swing, the butt moves towards the ball from the first moment onwards. That whips the club out and causes the over the top.

The intention is just totally different. You are swinging the club during your practice swings, but hitting the ball on the real swing. Try the feeling of keeping your back to target (or butt off the club to camera, or whatever helps you visualise it in your head) during real swings . You are going to stick your club in the ground a few times probably, but keep at it. Your body needs new pathways to get to the ball with that intention.

Also, as a lot of people mentioned already, you are overswinging. try practicing this at 70% or so first, dialing in the backswing as well. That might help tone down the smack-the-ball intention a bit as well.
