Nice video, but would have been even more dramatic (and illuminating) if you could have continued recording as you trouble-shot the problem
- test underlever left and right. tighten flange screw
- test sostenuto tab for noise
- test for loose lead (stabilize underlever and press front lead left and right to discern any movement). Could also use appropriate plier to squeeze.
- test for loose damper head (less likely)
- damper wire screw seems unlikely, as there's no indication of slippage - wire not loose in top-flange.
Damper seems to be impacting lift felt on tray upon return. Did you set that up for video purpose? or is that what the dampers sound like? You could also test for noise with a gentler 'up' tap, to see if it's as obvious, though I suppose source could be the same.

It's easy to test whether the lead is loose, since it is so conveniently inserted right at the front.
Put a little bit of CA glue on a small screwdriver, and butter the seam at the edge of the lead weight, so the CA wicks in.
You'll have your "yes or no" answer in seconds.

I'm with Wim on it being the flange not being tightly secured to the rail. Alternatively, loose lead in the arm.

Sounds like loose damper flange screws. Either that, or the head is loose in the wire.

Several dampers on this Steinway B make this peculiar noise. I can't identify the cause.
