You're a scooper... meaning you keep your hand under/behind the ball pretty well,(even though you do get around the side) .... that's good. Your swing bumps out to the right at the top of your backswing, quite a bit. This means the ball comes down towards your leg and you then have to correct it by flipping it back to the right at the point of release. This extra action makes it nearly impossible to have a smooth, relaxed swing... and robs you of ball speed. My guess is you do ok on slick lanes, and struggle big time on dry???
Keep your hand under the ball, but relax your arm. Think of your arm as being a rope with a ball at the end of it. This will help you to swing it nice and straight. Now, keep your hand straight behind the ball, and try to roll it end over end.... straight ball. This is how you keep from being on the side at the point of release. It will take a number of reps throwing it straight.... then,when you have that down pat, it's just a matter of adding a small amount of turn at the end of the release. In my experience, you will need to really work on the straight ball release first.... to override muscle memory.
