Squat form Check

[Abhijith1234]

Hi,

Recently I took a video so that I can verify my squat form and saw that I wasn't even reaching proper depth. Since that video was taken at an awkward angle I'm not posting that . In the next training session I decreased the weights and tried to squat to full depth.
Here are the videos -

But even in these videos I'm unsure about my form.

Concerns I had after watching these videos -
1) I see my hips are extending ( not sure if this is the right word) as I reach the bottom and the contracting when I come back up.
2) elbow position seems too high
3) Torso seems to be much more horizontal than required
4) Depth

I would really like some advice on how to correct my squat form.

Ditch the running shoes and get some squat shoes.

Stand more upright at the top.

Don’t look down so excessively. Find a spot a little further away.

Spine does something weird out of the bottom. Keep the back straight.

Elbows too high.

Correct these things and post another video.

The bar is too low on your back, which is why you're having most of the issues Sawyer pointed out.
Wear a cotton shirt and see if you can find a bar with a center knurl so it doesn't want to slide down your back.
Watch this on where the bar goes YouTube
Narrow your stance to shoulder-width so depth isn't so tough.

Thanks, the video finally helped me understand where the spine of the scapula is .
I tried to place just underneath the boney part that I feel behind my shoulders as mentioned in the video. Here is the video after moving the bar up - YouTube
Sadly I wasn't able to find a bar with a centre knurl.

My back stopped doing the weird thing at the bottom of the squat. I narrowed my stance width and found it easier to achieve depth ( I think I'm achieving proper depth in this video, but not completely sure. It will be helpful if you can confirm).

Also a little concerned about the back angle. Is it supposed to be this bent over?

And I wasn't able to get a weightlifting shoe as I was busy with work. Will get it in the near future.

Any other tips/corrections will be much appreciated

Thanks
