Can the video quality be significantly improved?

Question

Video processing

Here is a conditional video file, a conditional episode of a series or a movie. Video in FullHD format, 8250 kbps approximately, etc. I wondered if it is possible, having such a file, to make the quality of this video much better in "home conditions"?
Is there any way to convert it to 4k, improve the quality of all the details and raise the frame rate? Maybe there are some special programs that allow you to do this really efficiently.

Answer 1

Neural networks remake Soviet cartoons in 4K. They can double the frame rate on the fly (SVP - smooth video project). In general, it is possible, but there is no and never will be a universal "do it well" button.

Answer 2

Can. For example, the Gigapixel project. Surely there are analogues and open source
But over a good video card and a month so that it plows))

Answer 3

just add sharpness.
