As a two Hander, your elbows has to be closer to your body that is why you have a awkward and inconsistent swing. I can't tell cause I can't slow it down but are you using your right hand to help turn the ball? You can try cuffing the ball also. the one thing I stand by is "If it works for you, it works for you". One more thing is that you are rushing. Take your time to get set up. You get the ball in your hand and just take off.
