Ooooh - ankle mobility got you good on the squats!
Another joint to add to your mobility list!
Secondly, get some plates under your heels in the mean time - it will make a big difference. This ankle stuff is also shafting the squat as a whole, because you tilt your shoulders forward to balance out at the bottom (because your knees don't come forward enough), killing your core bracing.
Also, see how you draw a circle with your hips in the hole (ooh-err!)? As you tilt forward, you're pushing your knees back, too, which puts the strain onto your back and posterior chain. It's not necessarily a bad thing (unless your back is hurting, and you want to work your legs...), but it won't help your leg strength as your erectors are doing all the work.
Solutions? Pause them at parallel with just the bar. Find your stable point where your squat feels awesome (!), and sit there for a five count, and drive back up with the weight on your heels. Next time, find that point and try and force your hips apart to sink lower... ever so slightly each time.
Finally, one thing it's taken me a loooooooooooooong time to realise, is not to concentrate on holding the bar up on your shoulders (rack position looks much better, btw!), but on keeping the base of your neck jammed back as hard as it will go (to keep your upper back straight throughout the squat).
Deadlifts? It looks like the weight isn't over your heels, so you're pushing the weight back (using your quads) before kicking your posterior chain into gear. Instead of doing this (I do it!
), sit back into the lift and hump the bar.
