These are actually pretty good. Two easy adjustments:
1. Think chest up as the bar travels between the floor and your knees. Right now your torso miiiight be a bit too horizontal, forcing you to do a big swing of the hip joint after the bar crosses your knees.
2. When you go to full extension, the bar is a bit further away from your body than I would like. This seems to also force you to jump forward a bit to rack it. It'll stay closer if you really focus on shrugging harder with your shoulders when going to full extension.
