Camera caught a strange what appears to be a beam from the sky

Camera alerted to activity in the driveway. It appears to be a beam of some kind from the sky starting in the top left frame. You can see the beam hit through the two trees in the lawn, but terminates into an orb instead of hitting the ground. The orb periodically splits into two and reforms into one again. If you look closely there is a black line in the orbs when they split and reform, the line alternates from one side to the other. Once the orbs reform into one orb the line is gone. The beam also hits the siding of the house at the top of the frame at the end creating another orb reflection perhaps. It is not acting like a laser or other source of light beam. It never reflects off of the ground. We suspected it was the vehicle reflection that later passes, but it doesn't make any sense as it would be impossible to hit the top of the trees and leaves straight down from the sky. Also it wouldn't be moving all over the place like it is.
Activity starts 20 seconds in.
