But the truth is that the films which were shot in the 1950's were actually 4k cause the chemical reels which were used to shoot the movies are even 8k ready but untill the modern digital age no one  were able to get the original resolution of those chemical reels and now the studios are getting the original resolution of  those reels and one of the best examples is the Godzilla movie which is shit in the 50's

And nowadays many movies are shot in 4k cause they can edit and compress them into any format they need and want to.

There are even problems with the 4k video streaming if the video is streamed through the internet the internet speed should be 30mbps to 40 Mbps.a nd even higher end of and screens......
