Good call, it’s most likely bokeh.

Mick West incidentally does a number of quite good videos on UFO footage and camera phenomena.

Yep the bokeh takes the shape of the aperture blades. Typically they look like hexagons but I could see in this case of some weird military night vision it being triangles.
