Definitely looking good in the clips, just a few things that I could suggest that Chewy didn't cover -
1. The squats are nice and deep, form is very good, it just seems that the tough spot is getting those hips to push up and extend right at the middle of the ascent to keep things flowing smoothly from start to finish. Lockout gets strong once you clear that mid-point, though, so it's just a small portion of the total ROM that could be worked on to really make the numbers jump quickly. Judging by your form, it looks like you've got some pretty long legs, which always can make it a bit tougher, particularly when going low-bar position. I know people here rip on partials a lot, but I will say, if you can identify about where your sticking point usually, is, make it a point to throw in some heavy partial squats that bottom out at that sticking point. So, for example, if you find that you start to hit a rough spot about 8" out from bottom, then try setting the pins in the rack at that point and spend some time working at that position. Either multiple low-rep sets (maybe 3-5 reps) with what you'd normally do for 1-2 reps max at full depth, or, singles with around 105-110% or so of your 1RM at full depth. Overloading the weak spot really helped me in the past, might be worth a try to see if it gets you to blast through a tough spot!
2. Again, those long legs are going to give you a different starting position in the DL than others will have. Like Chewy said, your hips are coming up a bit fast before the pull gets off the ground, so you'll want to try to get those hips locked into place so the pull can be as effective as possible. Longer-legged people will almost always have to have their butts higher up for a starting position that's effective (unless you're one of those lucky few who can practically squat the bar upward when starting low), so you are probably VERY close to your optimal start, but your mechanics will definitely change the setup from how someone with short legs and longer arms would pull. Keep everything tight so that you're already properly tensed for a pull that's as effective as possible, rather than having the hips too loose, where it lets the pull make your body change in response to the movement of the bar. I'm still having to re-learn this part myself, it's definitely what's keeping me from moving up faster in my numbers, but it's getting there!
