Deadlift:
The biggest issue I see is that you're not effectively setting your spine in extension before you pull. This is STEP 4 and cannot be skipped. The blue book describes Step 4 as initiating a "wave of extension" of the spine that starts at the thoracic spine (Chest Up cue) and continues down through the lumbar. Your pelvis should tilt (Rip says drop your junk down between your knees). You should feel really uncomfortable in your hamstrings as they fight your spinal erectors.
Additionally, you're dropping your hips a bit too much and kicking the bar forward of midfoot on Step 3. So watch out for that too.
Squat:
You're breaking/bending at the knees slightly before the hips. They should break simultaneously and the back angle should be at its most bent over by about halfway down. Your back angle changes throughout most of the descent. So try to break at the hips sooner and more than you are right now ("master cue" helps with this).
On the way up you're lifting the chest and looking at yourself in the mirror. Look down, ignore that guy in the mirror, and drive up with your hips, not your chest (stay in the hips).
Keep working!
