Artificial intelligence (AI) has been used to create a stunning 4K version of the classic black and white film L'Arrivée d'un train en gare de La Ciotat. The 45-second clip is famed for the urban legend -- which is now thought to be false -- that cinema-goers fled the theatre when they saw the film for the first time for fear the train would burst through the screen. YouTuber Denis Shiryaev posted the remastered video on his site which is now in 4K quality at 60 frames per second. The upscaled and source videos look very different when compared side-by-side (pictured). This'upscaled' footage was created using neural network-powered algorithms such as Topaz Labs' Gigapixel AI and DAIN.
