Hmm, it's possible. I'm not buying a couple of those videos though.
The diamond shape you see in most of them is most likely caused by the camera having trouble autofocusing on such a small object. Still camera and
video camera autofocus works better if there is contrast in a scene which the autofocus can use to determine the distance at which the lens should be
focused. If the scene is flat (such as a clear or dark sky) then the autofocus can't 'see' anything and has difficulty doing its job.
I'm sure some one will ask "But the bright light, and pitch black sky; that's very contrasty, right?" Well, yes, but the light really isn't a
defined object that the autofocus sensor can 'see', not to mention the dot of light is pretty small. Very small objects in the distance such as a
plane or UFO will probably not even be seen by the autofocus because the area of contrast is not great enough.
The diamond pattern you see could be caused by the shape of the light, but is also affected by the number of blades in the lens aperture. See
Bokeh. Google if you would like to know more.
I'm not debunking the whole thing, but from experienced eyes, a lot of the lights are out of focus, and it's really difficult to gather any
definitive information about where the light is coming from. There is one video where you can see multiple lights on what looks like a triangle UFO.
Evidently the camera had an easier time focusing when it had multiple lights against the night sky. Notice though, that when the camera does lose
focus, you see the distinctive diamond shape of an out of focus light as seen in the other videos.
I'm betting that if the videographer had pointed the camera at airplane lights, a light on a radio tower in the distance, etc., that we would see
equal difficulty with the autofocus and the same diamond shape when it does lose focus.
