There's quite a bit wrong here. If you live in a city with a coach nearby, lay out the cash for some private squat sessions. It's nearly impossible to unfuck an asymmetry on video. If that's impossible:
- get your legs measured. If one's short, shim it....if it's some crazy muscular imbalance, you may be able to squat your way out of the imbalance (I did).
- your lumbar spine is terribly over-extended. You're fighting like hell to high bar squat with low bar mechanics. Post a video or photo of yourself replicating the pose from figure 2-13 in Starting Strength. Post this with a second video of a squat set filmed side-on.
