Draw a straight line from the sun, thru the clouds to the video camera. Of those three objects, which one is the easiest to move, the sun, the clouds or the camera?
The camera is the easiest. A fast moving camera is one possible solution.
The clouds. When moving, clouds usually change formation and pattern. Sometimes they don't.
A fast moving constant cloud formation could be a solution.
A normal video of the sun arc, sped up. One solution.
A.I. A.I. can generate fake video.
A quick change in earth's rotation could also be a solution.
And a Borg tractor beam pulling on the earth could be a solution.
Any of those could cause that video motion. There are probably more solutions.
In today's world, what you read, hear and see is probable. The age of illusion and delusion.
