@flarkey is the expertIt may be possible to validate the suggestion of the two aircraft refuelling without @eyeSpy co-operation.
As I posted above, there is another flying object in the video, a single dot of light moving in an opposite direction with a similar angular speed (blue arrow) that appears to be a satellite:
It passed near a bright star (left of the arrowhead) that can be identified as beta Cepheus, a.k.a., Alfirk. If we can identify this satellite, we can verify the time of filming and probably narrow down the camera location. Any takers?
I cannot see a sat on in-the-sky.org that matches at that time, there's Starlink (2121) that is close but its moving in the opposite direction.
Could be the location is off by enough to make it matter, but I don't see anything close on that trajectory either.
