I see a few things you may want to work on:
1. your grip - looks like you are gripping a baseball bat, Get the club more down in the fingers; allows the club to release. You are probably wearing out gloves.
2. tempo - (mind you I didn't say speed), once you set up, you "fire" and your swing is really quick, little transition between backswing and downswing. Take your time especially during practice. Work on your tempo. I started thread on tempo and a lot of people struggle with the same thing. I'm using "Heeeres... Johnny" to help me with tempo.
3. Upper body turn - once you get tempo working and you feel you have more time in you swing, work on getting more twist or turn in the upper body. I think about getting my left shoulder under my head. But don't "dip" or you will hit it fat.
During your practice have something to work on. If you are swinging incorrectly, doing it over and over again just ingrains a bad swing. I know you're making a video for the us to watch, but you are just hitting one shot after another without much thought to what is going on IMHO.
Nice practice area by the way.
