I'm not sure if the video above is real or not but I have personally experienced the ME first-hand. This is sorta how it went down:
[March 2016 I call my sister to discuss: Interview with A Vampire & Sex in the City]
Me: Hey Sis, fill in the blank: "Interview with ____ Vampire."
Sis: A vampire
Me: Really? I've always remembered it with THE. Ok, fill in the blank for this show: "Sex __ the City"
Sis: In the city
Me: REALLY? I always remembered "AND the city" ...
[FAST FORWARD 6 MONTHS]
Sex in the City is now called Sex and the City
Interview with a Vampire is now called Interview with THE Vampire
I call my sister and blow her mind when she realizes that the movie and show has changed back to the way I always remembered them ... I have not seen the titles change since then.
I made a survey and got over 50 thousand responses. It's not a memory thing from what I can tell. The people with photographic memories felt totally fucked.
It's definitely not a memory problem like others have claimed (e.g. Clif High).
Hi. I'm pretty sure it isn't real. I found the original here. The guy has 7 videos on his channel and they all include some sort of video effect. In this instance , going by the theme running throughout the rest of the videos on his channel, I'm inclined to believe he's just a VFX guy who started a creepy pasta video mystery channel.
This You Tuber gives you a good breakdown on how it could be done using motion tracking. As I also work in the same industry I tend to agree with him that it wouldn't be to hard to recreate with the right tools.
Still, either way it's an interesting story.
