Mike,
Not debating whether the video is fake or not, but related to my own metereological observations having lived in a subtropical area, clouds "behave" differently. For instance, mountain areas in southern Mexico are most of the time cloud covered because the constant east wind from de Atlantic carries moisture and condensates as it clashes with the hills. The opposite side of these hills is almost always dry with clear skies. From an aerial view it would look as if clouds were stationary for weeks or months. Another example is hurricanes in the gulf. It typically takes them 2 to 3 days to cross it from the caribean islands and reach, let's say, the coast of TX. In a 6-12 hr aerial video the displacement would look minimal. On the other hand, cold fronts in the plains have little "land resistance" and move fast. Again, not for debate, just personal experience from a different part of the world.
