I found just the head bobbing segments;
first part is involuntary motions that take the reporters by surprise,
then the second part is voluntary imitation that embarrasses the reporters:

That's actually a compilation of at least two cameras/phones with different vantage points.
The first one posted on the web was the view of Hillary from her left, with the lead up to the “short circuit” showing her consistent safe public self. That is to say among toadies, sycophants, boot lickers, and the media, but I repeat myself.
That sort of normal lead up is what makes the sudden transformation frightening, as witnessed by the reaction of that one reporter directly in front of her and asking a question..
The second view point, directly in front of Hillary and to her left, shows the bizarre sudden transformation and head movements, followed by her out of left field comment about the iced chai latte or whatever and then her recovery (?).
It was a sudden and spontaneous medical event.
My SWAG is another TIA or mini stroke consistent with with her previous falls, imbalance, persistent confusion, and weakness in the legs, witness the photos of her gripping chair backs, railings to remain upright. The current photo of the a pathetic climb up a short series of steps requiring two strong male helpers indicates to me, the condition is beyond pharmaceutical treatment.
In other words, it's all downhill, just the speed being variable. Sadly, I've seen thatcsort of thing before.22
