I'm surprised nobody has commented on the last part of your video.
First approach high - go around was the correct decision.
Second approach had you floating down the runway (too fast on approach?) and it looks like you touched down at the halfway point. You almost ran off the end - very poor judgement to continue this landing imho.
I was taught to land in the first third of any runway and use the second third for braking with the final third as a reserve.
