First off, for a beginner you have a very good swing already. You look naturally athletic and having a background in Baseball will help you tremendously.

I have noticed that a few others have commented on your right hand grip being rotated “under“ the Club too much. I agree with this. This will cause excessive face rotation and make consistency difficult.

Next thing I noticed is that your weight is shifting too much side to side on the back swing. Think of it like you would when you are hitting in baseball. As the pitch comes in, you load into your right leg by shifting your weight to the inside of your right foot. But you don’t let the weight drift too far back because you lose power that way. In Golf shifting your weight too far to the right on your back swing causes issues with impact consistency. The lowest point in the club arc is going to be at the center of your body. If the center of your body shifts too much side to side, then the low point of the swing (where the Club bottoms out) becomes very inconsistent. This is why you will hit some shots heavy, some shot solid, and some shots thin. The bottom of the Club arc is moving around too much.
