Form check: Squat, knee cave in, 260 lbs at 183 lbs bodyweight

[Diced]

My right knee (looks like the left one in the video) caves in during squat. I am trying to push it out, hence the wobbling knee. Is this normal/acceptable? Or do I need to do something about it?

I can send a video from the side angle too if need be.

Thanks!

Anticipate the bounce out of the bottom. Don't let it force you down deeper than you want to go. I would also widen the stance slightly (about 1 inch per foot) and point the toes out just a little more. These should create more general tightness and probably help with the wobble in the knees (which isn't too bad actually).
