looks to me like chromatic abberation…it’s an undesired byproduct of shooting with poor quality lenses…think of the album cover for Pink Floyd’s Dark Side of the Moon…with the prism and the rainbow emanating from the white beam of light…. well when this happens through a lens it looks like what you see in that video.

there are plugins that can do it….just google it.

good luck!
