Squats: Looks like a death trap of a stand setup. Those foot supports look like a trip hazard. What the hell was the step coming out of the rack? Your squats are mostly high. Your face is pointed in the wrong direction. You have a lot of knee slide. Shove your knees out, push your hips back, keep your face down.
Deadlifts: You currently have the bar too far forward. Get it over midfoot. Do not squat down to grab the bar. Bend over with straight legs and take your grip. Bring your shins to the bar from straight legs. Squeeze your chest up. Squeeze until it feels like your face is going to explode.
