Lots of issues here...
1. You are not hitting depth--this is apparent even though the uprights are blocking the view.
2. You are not shoving your knees out.
3. Your knees are moving through the entire squat--you should be setting them in position about 1/3rd of the way down and keeping them there.
4. Watch your bar path--it is not at all vertical. If you fix 2 and 3, that should improve.
By your left inner hip, do you mean your groin or the front of your pelvis where it meets the leg? If it's the latter, your knee slide could be causing it. Re-read the squat chapter, especially the discussion around the "interesting type of tendinitis".
The vid angle is kind of useless for diagnosing asymmetric problems. Can you film yourself from the back or at a 45 degree angle?
Finally, consider getting some lifting shoes. Squatting to depth and keeping knees in position are both easier when you have a non-compressible heel.
