I'd also like to point out that, if you look carefully at the
panorama which I produced from four frames of the video


you will see that while the object moves in a smooth arc upward
from the landscape, the video camera is not so steadily held.
Therefore, if faked using graphics software to simulate the
object, the software involved (or the hoaxer) would have to have
determined the position of the faked object not according to the
bounds of the frame, but according to reference marks (i.e.
objects) in a set of frames where field of view is constantly

Prior to realizing this, I had believed that the fake was fairly
simple. It is still not impossible, but fakery is made much more
complex by this realization. In fact, it requires either that the
object be placed by hand in each frame, with some fairly complex
calculations as to where the object would be in the frame, or
that a set of frames, with each frame larger than the dimension
of a video field, be created and animated, and then an artificial
"camera shake" be superimposed on the resulting animation. This
is much more difficult and time consuming than simply putting an
animated brush into a prevideoed scene, with a few blocked out
regions where the brush is not allowed to show. It is also
possible that an artificial camera shake might be found out
through an analysis of the camera motions.

At any rate, if the path of the object were a straight line when
the panorama frames were set with their bases or tops aligned, it
would be much more likely that we are looking at a fake. But this
is not the case. If the frames are positioned this way, the
object follows an undulatory path which "just happens" to be a
rising arc when the camera positions are aligned by reference
objects in the picture.

That "just happens" is what makes this video hard to fake.
