Is the original footage actually from channel 7 news in the first clip. If it's from a news camera would there be that much movement in it, and news outlets are known from time to time to discuss UFO's caught on camera. I can't see them passing up on an opportunity to report a UFO if they actually caught the original footage...
I still think it's a reflection - the clear break in the 'structure' mimics the lighting on the building below it.
He may be filming his monitor.
I wonder if there are independent sources for the other two examples in his video.
(not really worth looking into deeply though, he obviously is traffic hunting)
