It also tilts/wobbles a little (at about the time it's passing the reporter's head) the way a gliding bird often does.

Yeah, I always get a kick out of when they invert videos, emboss it, and act like it actually proves anything is actually there or not.
I didn't say it is.
It is not manipulation of an object to create an entirely different object. I.E. Turning a blurred picture of a turtle into a cleaned picture revealing a beach ball.
That's what I said.
The algorithms that software like Photoshop use will interpolate existing data to enlarge an image and make it seem like it has higher resolution, but no new data is revealed.
Here is an example of an image cleaned up after applying a Wiener filter.
Typical deterministic filters are designed for a desired frequency response. However, the design of the Wiener filter takes a different approach. One is assumed to have knowledge of the spectral properties of the original signal and the noise, and one seeks the linear time-invariant filter whose output would come as close to the original signal as possible. Wiener filters are characterized by the following:
Assumption: signal and (additive) noise are stationary linear stochastic processes with known spectral characteristics or known autocorrelation and cross-correlation
Requirement: the filter must be physically realizable/causal (this requirement can be dropped, resulting in a non-causal solution)
Performance criterion: minimum mean-square error (MMSE)
