I wonder if the guy videoed a bright planet using a "star
filter" or something like that on his lens (a diffraction filter
with three gratings that are 120 degrees apart).

He might have used a color filter as well to make the light
approximately monochromatic to avoid color blur that would occur
when a diffraction filter is used with polychromatic light such
as starlight.

Tha latter portion of the video looks like an "emboss" version
of the first part.  Pulsations of the image could be a
combination of "focus hunting" by the camera and atmospheric
scintillation.

If all this were to turn out to be true, then it would be a
hoax.
