Deadlift: You really need to watch and apply the
5-step deadlift set up video. You're too far away from the bar and are "squatting" the deadlift.
Squat: This isn't a good angle as I can't see your grip or your stance (both of which may be off). The bigger issue is that you're doing some sort of amalgam of high bar and low bar squat which is pretty wonky. If you're going to do a low bar squat, you need to break at the hips and knees at the same time and immediately get your chest aimed at the ground. Push your hips back more and stop your knees' forward movement. You are also way too loose and are going way too low.
