There are many standard objects in the video -- stop signs, telephone poles, moving automobiles, stationary automobiles, etc. -- which can be used to
get close estimates as to distance (and even a pretty reliable altitude at one point)... all of which can be related to arc length / angular size...
and then, with a reliable frame counter, converted to object speed. (We could be surprisingly precise if the videographer told us how far his wife was
from that stop sign.) But the bottom line is that these objects are moving significantly faster than 50 mph horizontally, even after having just
*lost* kinetic energy.... Puzzling. I'm positive that there are RC objects that can move this fast, straight and level, but am highly doubtful that
anything exists with this particular combination of speed / size / maneuverability / stability.
Also, their actual brightness is puzzling. You've got a nearby street lamp partly saturating this camera with light, and smart phones are already
notorious for reducing the apparent brightness of objects in these settings. Yet these objects still appear to be quite quite bright.
I'd say CGI before RC, but who knows? Not easy to dismiss.
Another thing: watch closely at 13-14 seconds, as the two objects get near each other. There appears to be something extending from each of them, even
at unexpected angles. At first I thought... "okay, maybe it IS RC, and these are the analogs of wingtip vortices." But why only one? And, they occur
out of alignment with the "aircraft's" longitudinal axis, and also when the one object is not even maneuvering violently. So... probably not that.
Hmmmm.... My next thought: kite streamers, visible only when the kites are making sharp turns. But, nope, not IMO. Same reason as above... AND one
goes between two distant telephone poles, apparently under the hanging lines.
Can anyone intelligently address brightness / luminosity / radiance issues?
How easy would it be to pull this off with modern CGI techniques? How credible is the OP's story, setting, etc.?
