Well, that's a Middle Marker tone, I think.
I think it is fairly clear that someone had their thumb on the trimmer for some considerable time during the pitch manoeuvre to catch the altitude. Why, is another matter. An incorrectly learned response? Out of fatigue? Out of fright? A mechanical malfunction? We do not know at present, but it is likely the fault lies with the trimmer.
As to the question of the 'noise' on the video, the cryptic poster was referring to the trim-wheel wizzing for quite some considerable time. This is not a noise you are likely to miss, to comment on, and to react to, if it happened of its own accord. So perhaps we can rule out mechanical failure.
