Im going to approach this from a simplistic practical perspective instead of my usual tone of discussion. There is good things about your stroke pattern but lets just concentrate on the areas needing improvement.

First thing you have got to get rid of is when you start back you are looking at your hands or clubhead... you should be looking at the ball. This is a terrible habit and one that you should get out of as quickly as possible. The habit is usually formed whilst doing practice swings at home...etc.

I also don't like the head movement on the downstroke either. It makes it alot easier to hit the ball when your actually looking at it.. Just think about the area you are standing in, not the target then "Hit the ball hard, it will land somewhere" - one of my favourite quotes.

It is hard to know for sure on video but just have a great sence that there is some grip 'slippage' in your stroke. You wrap your hands around the grip of the club and then they just 'hold'. The grip itself shouldn't change throughout the stroke.

You really don't have much of a pivot on the backstroke. Maybe a misconception is to blame about the hips resisting the shoulder turn which is incorrect. The shoulder turn drags the hip turn. Your pivot train on the backstroke is halted at the hip turn which restricts the shoulder turn. Your total inability to turn probably means your at the point where you may need to exaggerate the hip motion till you can learn to let the shoulder motion cause and 'drag' the hip motion again.

Your start-up is off plane. Learn that the pressure you make on the club at the initial moment you start to preform start-up will send the clubhead on an orbit... try and make that the correct orbit....
