I'm replying to this again because I had mistakenly thought you were referring to the clouds in a different video which didn't have clouds.My point is: why are the clouds so defined? Do we expect to be able to see them so clearly given how out of focus the camera needs to be?
So the clouds in the leaked navy video. They have soft fuzzy edges. They look normal that way because clouds, especially thin clouds, can and often do look that way, especially with NVD.
Remember that the fuzzy region is going to be about as thick as the diameter of the bokeh, because it is in fact lots of faint bokehs all along the border.
If you take a look, the clouds are no more defined than the width of the bokeh.
The clouds are not "so defined." It's just that we expect them to look soft and fuzzy, so they look perfectly normal that way, and defocus doesn't prevent them from looking normal in an NVD.
