That video really does not make much sense.
Bokeh just means the out of focus area of the image.
If that area is contiguous colour or mottled pattern then it's just called bokeh, if there is small or point light source it takes on the shape of the aperture this is also called bokeh but often referred to as bokeh balls if the aperture is circular or near circular, if not then the balls take on the shape of the aperture.
"There's no aperture inside this night vision google thing", almost every optical system has an aperture, its the most fundamental part of a camera, the most basic camera a pinhole camera is literally just an aperture.
The aperture is just the hole through which light travels. In most camera systems this specifically refers to an iris or adjustable diaphragm in the lens along the light path which can be adjusted to reduce or increase the amount of light travelling though the optical system, this also affects the angle from which the light rays are gathered, allowing more of the depth to the be in apparent focus.
High quality photographic lenses often have 6+ blades because the quality of rounder bokeh balls is considered desirable by photographers.
In a 3 blade aperture, this is the shape of a triangle with rounded edges, one of the advantages of the 3 blade aperture is the ability to completely close the aperture.
