You also appear to be doing a high bar squat. Is this your goal? I am, in general, confused about what you want. If you are trying to do a low bar squat, I would tell you to change a number of things. Further, I would tell you to send me a set of five because a limit single doesn't work well for form checks. Lastly, slo mo video effects while neat only serve to further confuse what you are doing.
