I suspect it is what the poster is referring to. I remeber when the smart
bomb thing was all the craze, in the TV broadcasts the shot would often zoom
as the missile flew down the air-duct or into the open window etc, but the
one's I saw were clearly done afterwards by zooming the video image,
resulting in tell-tale pixelation.
