Deadlifts: turn around and look away from the mirror. Let's see the set up - the bar is going forward at the start so you're either set up wrong or not staying tight enough (probably some of both). Narrow your stance. Why sets of 3? Why straps? Why ars you letting your breath out before the bar is on the ground?
Squats: are you doing a high bar squat on purpose? Need to know that before offering much commentary. Regardless of whether you think you are doing high or low bar you are way too loose, your head moves too much, and your reps are inconsistent from each other.
