The video that made me ask this is this one [https://www.youtube.com/watch?v=djV11Xbc914](https://www.youtube.com/watch?v=djV11Xbc914)
A-ha: Take on me in 4k. How is this possible when 4k didn’t exist when the video was made?
In: Technology
That video was recorded in 1985 on film from my understanding.
Film itself has a resolution way beyond 4K depending on the grain size. As long as the film is preserved, it can be re-scanned using a higher resolution scanner.
We will probably get an 8K cut in a few years.
