Hi ya, Brent. Your squat looks ok from that angle, hips lower then knee, back/core kept tight through out the lift. I can't say how your knees are tracking from there.
Be sure you are driving your knees out on the way down and back up. to engage the gluts and hamstrings too.
For the soreness I Don't know how you already warm up, but I'd add this (WFS)

I'd roll the gluts, calf stretch and also roll the lower back too. I hope this helps.
