What @FlatsFarmer said. First thing I noticed is that you started neutral and your head immediately drops once you break at your hips. It’s going to pull you forward.
You could experiment by bringing the grip in close, not too close if you have poor mobility. Use a talon grip (thumbs over the bar instead of under) if you struggle with it. Closer you are the better stacked you’ll be.
Your feet are playing dance dance revolution and you even lose your footing. This could be because of poor mobility, I suggest if this is the case, angle your toes out more. It’ll open your hips up and it does put more emphasis on your adductors but it’ll feel much more comfortable and easier for you. You should still experiment with that regardless if you haven’t.
A cue I use is two things, Big Air into the belly. And a second cue I use before I break at my hips (NOT the knees), is to flex my quads. Try it.
Walkout should be effecient. Straight up. Not dipped forward or back. And two, three steps if you can. Ed Coan explains this pretty well I’ll try to find the video when I can. Take it slow and take your time on the setup
