I'm not sure how to describe these plasma light UFO's that change color too fast to be recorded by a video camera. This appears to be real to me.
It reminds me of this sightining:
It looks like digital zoom on a star. if you have a mobile phone or a digital video camera take it outside when it gets dark and try and zoom in on a
star or airplane or other light in the sky and you will see what I mean.
Looks to me what happens when you film a star or a planet and shake the camera around a bit.
I seriously doubt there is anything more than that in these videos.
