The video contains two objects: The building and the object. The craft appears to move slowly from right to left and then appears to move (with dramatic apparently-instantaneous acceleration) to the left, out of frame. The movement the camera makes doesn't grossly affect viewing of the image because the distance between the building and the object remain constant, minus the lateral movement which appears steady. However, in the very last frame before the object "takes off" to the left, the camera's motion causes the building to move down and to the left but the object
stays in exactly the same place it was a split second earlier and then goes through the light-up sequence before zooming out of frame. Here are the two final frames (IIRC, right at the end of second 1:04 and beginning of 1:05):
I placed the images side by side so that you could see that there is no vertical movement in the object even though there is vertical movement in the building. There is also no horizontal movement but you'll need an image viewer to see that. This "persistent" quality of the object leads me to believe that it was post-processed into the video.
If you are unable to see the effect that I'm talking about, save both images and view them in a picture viewer (like the free, awesome InfranView). You can switch back and forth but you'll see that the craft "sticks" in the same spot even though its placement should move with the building.
Now, it's possible that the craft chose that moment (a split second before it turns on it's lights and zooms away) to
jump up but it's very unlikely that the movement would be exactly matched by the camera's random jittering.
I, uh, sometimes like to analyze videos very closely. It's sort of a hobby of mine, though not usually spatial stuff like this. I don't think the person who uploaded it knew that it had been processed otherwise they would not have included the very slow slo-mo. If you don't stare at
either object but at the space
between them you can see it (if you've got an eye for such things) at full speed. And in the slo-mo it's really noticeable. You can see other, minor, tracking errors if you use this technique but it's most apparent right before the jump.
Not to be a complete downer, the best UFO or at least "What the hell is that?" video I've ever seen is from Nellis AFB. There is an object which appears to change shape over time, sometimes quite rapidly. One point which is not often made is that it appears the camera which filmed the incident was an infra-red camera so bright spots equal hotspots or outgassing of some sort. There is a short
clip on YouTube but there are longer, much higher quality videos if you search very, very thoroughly on-line along with transcripts and analysis.
I personally believe that it's not a spacecraft but an extremely unusual atmospheric phenomena. Back before
trolls, pixies, gnomes, etc. had been photographed regularly and become "old hat" among the meteorology community they too were openly doubted or chalked up to something else. Blue jets, especially, are the most incredible atmospheric phenomena I have ever heard of and it's too bad more people aren't aware of the them and other newly-discovered wonders of nature.
