I would say that the reason you missed the lift is the timing is wrong in the clean. You apply much more force than you need to the bar. In the second clip, the bar even leaves the screen. Then it comes down to smash your ass into the ground.
There is a strong correlation between how good a lifter will do, and the distance the bar will "fall" before being caught. Both in the snatch and clean.
So what do you do about this? Well. A great revelation for me was that you cannot think yourself into lifting better. The explosive part of the lift is over in what, 1 second? You need to do the right drills.
Start doing cleans from a completely standing up position. Work the timing in. The timing que is "when the bar is in it's highest position, I will sit just under with my elbows up and catch it".
When you got that. Progress down to start at the middle of your thigh. Keep doing it until you have the timing in your spine. Then go down to just above the knee. Same thing.
Lastly, do the full clean, and use a perfect timing every time.
And whatever you do, never, fucking ever lift in front of a mirror. You want to feel how the perfect lift feels. Don't let your eyes take over.
