The snatch video says it's private.
The bar path from the floor to the knee is a little too vertical. The bar should be moving back at an angle toward your body right when it leaves the floor. Since the bar is moving vertically on the 1st pull it's automatically causing your weight to be too far forward, thus bringing everything else forward. On the 2nd pull you move your hips into the bar rather than pushing the bar into your thighs. If you freeze the video right about when you make contact with the bar, you can see that you're way up on the toes. Try to bring everything back more and stay flat-footed longer then drive straight up on the 2nd pull.
Also, on the 3rd pull make sure you're pulling yourself straight down with your elbows UP and OUT. It looks like you're taking them back and around the bar.
On a couple reps it looks like you're dropping your elbows down during the dip. Bring the elbows down and out slightly before you even dip and keep your upper body stationary through the dip and drive.
In the split position, keep your back knee soft so that you're able to absorb the weight with your hips straight down. The reason you're moving forward on some reps is because you back leg is locked out and you have no choice but to lunge forward. Keep a little bit more weight on the back leg when you split.
