Photo and video evidence is far from being clear cut evidence of any conclusion. Some weird-looking things have rational explanations like syncing of an object with video frame rate.  Check out this strange bird video captured at 20 frames per second and thus the birds wings appear to not move. 

Also, people are terrible at spotting fake photos. The study in Cognitive Research journal is publicly available:  Can people identify original and manipulated photos of real-world scenes?

Don’t assume some odd photo or video is paranormal. It’s almost certainly a result of a physical or technical factor that produced and unexpected and unnatural-looking result. And NEVER discount hoaxes. They are so easy to pull off.
