This is a distance shot with Edna Cintron waving.
It is a bit over two seconds long.
78 frames to be exact.
Here I've increased the brightness.
Notice how her waving creates subtle
shadows that aren't even visable at the original size.
The footage seems to waver because of heat rising distorting the light before
it reaches the camera.
There would be no way on god's earth of animating this sequence. Between the
random nature of rising air currents and the subtle shadows keyed to her waving,
it bears all the hallmarks of a perfectly natural event.
