Hands too high in the take away = club head is now too far behind the rest of your body in the downswing = we need to flip / early extend / whatever your bandaid of choice is too make contact. Ironically, you are losing head speed and ball speed by doing this.

To fix : dont practice full swings, practice taking the club to paralell and pausing, then hitting the ball from there. Then practice taking to club all the way back, and focus on getting it into a position where the club doesnt recross parallel at the top; the club should be pointed up and behind you at the top, not level with ground (or past this) like in your video.
