God, there are so many fake videos out there. If you have after effects and 20 minutes, you can do this.
The great thing about perspective is a vanishing point never lies.
If this video wasn't doctored, the lines you see would all converge at the same point (in the yellow circle).
I mean, they aren't even close.
What this tells you is the person who made the video shifted the perspective in a program like after affects. It is the reason why it is so zoomed in and cropped. The effect would be super obvious without cropping out all the garbage the program would produce on the outer edges of the film. It produces what is called a "pulling" effect where the distortion creates pixel stretch that looks like the film is being stretched on a piece of latex. It also would create large black spots in the corners where the film is bent and there is no additional information to fill that real estate. Look in the upper right hand corner of the video going around....you can see some of it.
The other thing perspective shows you is how angles that are 90* should display if the item is un-doctored. So things like the yard lines and hash marks create 90* angles where they meet (the green box). From that, you can show where the hashmarks should display if this perspective is unaltered. Again, not even close. With how the yard lines display, the hash marks should tilt slightly downward towards the end zone, they do the opposite of what perspective says they should.
This end result can be accomplished fairly easily by anyone who knows what they are doing and it is convincing, until you do the vanishing point test. This was something my college professor did a lot with hollywood movies to show how special effects don't need to be perfect to completely deceive someone watching it.
The easy giveaway is Lewis though. Look at his stance on the left of the picture. He's somehow able to run forward while leaning backwards, which obviously looks entirely unnatural.....because it is.
There is no video that exists that is conclusive. If there were, it would have been shown a long, long time ago. At this point, there's nothing anyone can do. Ohio State won, Michigan lost but the amount of time Ohio State fans are putting in to making fake videos is pretty funny.
