Can't see where the bar is on your back because the plates block the view. It's hard to tell from this angle the width of your heels, but it looks like they need to come in a bit and turn your toes outward more to about 30 degrees from parallel. Sit back more once you find the sweet spot that keeps the bar over the heel of your foot. It's pretty evident from the video that your bar path is not straight up and down, consequently you struggle coming out of the bottom. Trace a line in your mind from where the bar starts in space to where it ends and you'll see its 5-7 inches forward of your heel.
