Necroposting, sorry. Just didnt read this thread until now.
Was there a conclusion? Given its a screenshot, not the video, it seems likely they posted this one shot because its the most interesting. If you saw the 4 second video and it shows this moving across the screen quickly you'd know it was just a balloon/air object, and not a sphere on the ground or a water puddle. The lack of video seems deliberate.
Its not a water droplet on the outside glass. It cant focus and be sharp like that. If its an internal camera fault(on the focal plane) then its (a) huge, and (b) going to be seen everywhere you look at the same place on the screen.
Highly unlikely this is a photo of a monitor.(and hence a reflection). The screen capture/image is exactly the size of a video output from the camera.
The camera setting is the EON daylight camera, at 1500MM focal length. Common in MX systems.
Terrible focus setting. Set at infinity, with trim at 99% (the maximum) implies there is something wrong with the mechanism/tuning. It is at absolute maximum focus, and it still isnt sharp.
Spatial AND
temporal on! Temporal filtering, on a sunny day, in a fast moving aircraft, is a very odd choice. Temporal uses time to calculate an average of the view over multiple frames, and present a final pixel. Very good for cutting through haze, from a sandstorm or falling snow. So, maybe there was blowing dust this day? But to get it to work when you are moving quickly takes some skill, because if you slew the camera too quickly all you get is a smear of images everywhere. Like cheap 80's sci-fi ghosting effect.
The locations and overlay descriptions from post #22 look correct.
From Corbell's instagram on this photo:
So, even the original source knows it isnt a shiny puddle.
My 2c : It is a balloon moving through the frame, from either blowing in the wind, or the aircraft moving relative to it, keeping it in frame for only a brief moment.
