I'm not going to give you advice on your swing, but I will tell you this: the next time that you shoot video of your swing, put the camera in line with your toes, not the ball. You have the camera in line with the ball, which will make you look like you are off plane even if you are directly on plane. Easiest way to do that is put an alignment stick or a club on the ground, set up the camera in line with that, then come back and have your front of your shoes just barely touching the stick or club and then place the ball on the ground.
