Visually speaking I would give that video every credit. I can't spot any of the usual failings due to video compositing.
But, purely on behavioral grounds, from 100s of stories that I read, UFOs simply don't put up displays like that above major populated areas. Simply, there is the way how UFOs behave and this completely breaks all trends. I am pretty sure that is fake.
It is impossible that in such a large city of few millions of people nobody else noticed anything. When UFO flew over Phenix, Arizona 600 people reported seeing the craft. When a similar event happened in Jerusalem there were 3-4 simultaneous mobile phone recordings.
