My buddy Marco in Austin bet me $50 a viral stadium crowd clip was real, and the shadows proved him wrong
Marco sent me that clip of 80,000 people supposedly doing a wave in an empty stadium last week and swore it was real. So I zoomed in and the shadows on the seats all pointed 3 different ways, plus one guy in the corner shows up twice in the same frame. Took me about 20 minutes to spot the copy-paste loop. He still hasn't paid up, so does anyone know a good way to prove a clip is stitched together before they start arguing?
Marco's not crazy to think it's real at first glance, but your shadow test is the right move. The 3 different shadow angles are the giveaway though, not the shadows being present. One thing to check: slow the clip to 0.25 speed on your phone and count how many people in a row do the exact same arm motion at the exact same millisecond. Real crowds never sync up that clean, someone's always half a beat off. Also look at the edges of the frame, stitched clips usually have a person or rail that gets cut or warped where the loops meet. If you see the same section of seats repeat after 8 to 10 seconds, that's your proof. Tell Marco the $50 is late fees at this point.
