Looks very CGI to me.
The "UFO" moves far too smoothly and too precisely and sits too stationary in the video for me to think it's real.
It just lacks the feeling of a real object, IMO.
Interesting how the cameraman 'follows' the projected path of the objects and then zooms in right where they would emerge from behind the house. He
doesn't side step or step back to try to keep them in view. Just turns the camera "assuming" to catch up with them.
Doesn't feel right to me and just looks fake.
