I can tell you using a 3D software like 3ds release x you could just create a UFO with a tracker like link that keeps the object stead with the
moving or panning video. you could add a shake plugin but it won't look as good as if you were to re-record on a high resolution large screen and
just naturally zoom in and out, crop out the tv frame and anything outside of it and it looks fairly realistic. with the pixel counts of todays tvs
it's very difficult to prove it's fake unless you have high end analizing equipment and the original video.
this looks to be a first attempt of the same object, in the exact same country but probably someone using a satellite google like map
it didn't come out as good
