Two cities, each on the other side of the world, captured on old film which has been digitized, colorized, and upscaled using neural networks to 4k and 60 frames/second.
Some of the technical details about what Denis Shiryaev, a YouTuber known for restoring vintage videos does to achieve his magic:
4k upscale – Each frame can be upscaled using specifically-targeted data that perfectly aligns with your footage. Our neural network will “redraw” the missing data and increase the frame resolution 4x or more.
FPS boosting – A neural network trained via slow-mo movies will artificially generate additional frames for your footage. Even 14 fps films can easily be boosted to 60 fps.
Denis also ran his algorithms across the famous Trip down Market Street film (recorded just days before the 1906 earthquake). As he narrates, over the course of half a month, he upscaled the origianl and transformed it into a 50,000 frame, 380 gb file, using the algorithms to fill in information that was not captured in the original.
