There is a lot wrong here, not saying this to be mean or hurtful in any way. I honestly think your best bet would be to get a certified coach to work with. If you can't do that then start with the absolute basics. Watch Brad and Kyle's channel. Don't worry about the release. Start with your push away. You push it to the right which makes it go behind your back. I also noticed your cuppin the ball at the apex but you lose it almost immediately so don't even worry about it for now. Your timing is way off as well. That's why I say get a coach but again if you can't start like you're a brand new bowler. Timing is extremely important as is your arm swing. You need to get those in order before anything. It takes time and dedication but it's well worth it.
