When video editing gets so natural and convincing
that it becomes a little disturbing.

Video processing software is very clever these
days. I don't think it's done by video editing
though.
I think there's something extra inside those
switches and some tricked out LEDs. Each
LED is paired with a switch and switches
itself on when the switch does its thing.
eg. A switch could put a certain frequency
signal on the wire that a LED can respond to.
It could even send out a digital signal whenever
it opens/closes (maybe like an SPI interface).

Old trick. There are hidden diodes. Not a video trick.

There is probably no need to edit the video! Some years ago, there was an
article in the german magazine ELO showing such a circuit. Inside the
battery there was an astable, and there were diodes hidden below the
switches... I seem to recall it was called a "Paradox Generator".

I was thinking of a video transposition because of the green background
which is used in broadcasting to superimpose video.
Where would the diodes be hidden to control each LED since it appears
that only one wire is used in the series ckt. ?

I recall this trick from years ago but don't remember the actual
details. Faking it with video would be very easy. All that would be
necessary would be to have the switches do nothing and edit in the lit
LED's later.

Yea! I agree. But someone said there were hidden diodes..

In the comments, there was one suggestion (in German) that presented the
possibility that the battery was an AC generator, and diodes could be used
in the switches to produce this effect. It seems to work for the cases where
there are only two switches and LEDs in series or parallel, and one of the
LEDs would be connected in reverse. But in the case of three, I don't have a
good answer. Must be magic...

Must be a bit of sneaky hidden gubbins - the middle LED has a shunt inductor
(hidden of course) and maybe a DC blocking capacitor to the LED itself.
With HF AC, the inductor could be a tiny SMD hidden under the LED body.

With all your experience in electronics you have never hear of PFM?
