Still doesn't look like you're setting your knee angle quick enough when you break the knees and hips. That's why you're rocking at the bottom and end up doing a good morning.
Push your hips back more and set your knees out in the first half of the squat. You might end up setting a bit more of a horizontal back angle than you are currently. Don't fret about this.
Also, resist the urge to lift the chest up when you hit a sticking point. Think "don't let my chest drop."
