Flat Earth At 1999 ft !!!

The name of the video is ( Bulb Changing on a 1999 ft. TOWER! )
Look at the background video of the earth. Some of it is flat,then at a different angle it gets fisheyed / round at a different angle. So does this prove or disprove Flat Earth stuff?
P.S. Could not embed this video.
