I'm concerned about these elbows that look cranked up. I don't think I remember seeing this, but may have been from a different angle. At any rate, your elbows are too high up, which means your upper back is likely not in extension. Without your upper back in extension, it's going to be tough to get confident in leaning over, sending the hips back and keeping the knees in place.
Lift your chest and pull your elbows down so the upper back can get set into extension. This should keep the bar pinned in place. Then lean over from the start and send the hips back away from your feet. This should keep you off your toes and stretch out the hamstrings to get the "bounce" we're looking for out of the bottom.
See if that helps. We still want the hips and knees to break at the same time, just aim your nipples at the ground and in between your knees as you start the squat.
