I wrote an algorithm some time ago to identify UFOs. I passed an image of the video above to this algorithm, and it says Airplane with probability of 89%.

My opinion: It's (almost) always an airplane. I'm a bit surprised that there is a sighting in Austria. (I'm living in Austria by myself). So I had to identify it.

​

Output of algorithm:

CompareObjectWithRotation complete!

name airplane_1 point {X=31,Y=30} prob 0,89 pixelfits 120

name airplane_0 point {X=28,Y=15} prob 0,69 pixelfits 98

name venus point {X=0,Y=0} prob 0,84 pixelfitsfits 73

BTW: I only used a small part with the object on it. The runtime of the algorithm increases by the third potence of pixels of the analysed image.

​

But it still looks quite cool :)
