We coach the press with more hip movement than this. Lots of videos on the forums.
Ok. Will try to implement more hip movement on Saturday.
You're moving your hips but failing to "whip" back up: you're thrusting your hips and just kind of freezing them there. Think your upper body as a lever that "flings" the weight up after the hips are thrust forward.
Today I really tried to move my hips as far forward as I could, and in doing so I started to unlock my knees again, despite squeezing my quads. When trying to “throw” the bar up, sometimes it looks like I’m getting a double bounce.

Better hips. Now, look at your feet. Get some lifting shoes.
Your grip is creeping wider. In general, you have a "looseness" in your body that's letting the energy of the bounce (which you are correctly executing now) dissipate through it. I think thay might all come back to your grip. Stack your elbows more in front of your shoulders. At the bottom position, try cuing your elbows "in", almost like the rack position of a clean or front squat. Get the "platform" you're launching the bar off as tight as possible. Like Rip says, shoes will also help.
