I Did Stumble Across The YouTube Video That Was In 60FPS and it was The Star Wars Holiday Special.
A while back, I had installed some “60 FPS filter” plugin that didn’t seem to be working, and I forgot all about it.
Then I downloaded the Holiday Special and I think it finally started working…and it gave me some serious motion sickness >_<
At least, that’s the only explanation I can think of. After I burned it to a disc and watched it on a different setup, it didn’t quite have that “soap opera look” anymore.
