Way too much movement off the ball in the backswing. That's a perfect recipe for inconsistent striking. Look how far your head goes away from the target, and how you never get it back anywhere near its position at address. That likely means you can't get your weight forward enough in the downswing, which means you can't get the low point of your swing arc in front of the ball, which means you're entirely reliant on timing your release to avoid hitting it fat, then thin, then fat etc.
This is happening because you are staying in flexion too much in your backswing. You need to let the right leg straighten more, which will let the hips turn on a more tilted angle (yours are too level), which will start giving you the extension you need to keep your head steady. To you, it's going to feel like the whole right side of your body is stretching out as much as possible, from ankle to shoulder -- like you're shoving that shoulder up to the sky. You are flexible enough to not need to think about "turning" at all. Just streeeeetch out that right side and let your left shoulder move down under your chin.
