Anyone looking at the sky near sunset the past couple of weeks might have noticed two particularly bright objects. One is Jupiter (in the east), the other is Saturn, in the west. Assuming this video was taken near sunset, I’d bet that if she looked at that “orb” with a decent telescope, she would see Saturn and its rings.
For decades, people claimed to see UFO’s, Sasquatch, Yeti, etc. Once everyone had a camera in their pocket all the time, you would expect someone, somewhere, to get a decent picture or video of one of these things. And yet, to this day, I have not seen a single decent, convincing photo or video of anything. And that is because none of them do, or ever have, existed.
People, generally, are not very bright.
The video wasn’t taken near sunset...
Cell phone cameras do strange things when highly zoomed, as they struggle to focus (because the subject is too far away). And as you said, atmospheric distortion also comes into play.
That was no cell phone. That was a high en camera with a zoom lense. You can hear the mechanism every time she adjusts it.
