UFO Light Show Above Power Station, East London. Real Or Not?

There is a lot of debate over this sighting - especially how the object just beams out of the frame like something from a Star Trek episode. It would be helpful if anyone with video editing experience could analyse this. No date given either, which is suspicious. We're assuming the footage is from the Deptford Power Station on the South Bank of the River Thames in Deptford, South East London.
