Original Note:
The video is pulsing because the star is scintillating or "twinkling." The shape is due to the shape of the optics from the camera being out of focus and due to the aperture blades being slightly closed. https://flatearth.ws/bokeh https://astronomy.com/magazine/stephen-omeara/2015/10/out-of-focus-observing
