What I'd like to try at some point is to let some AI/ML model process the frames, and instead of necessarily scaling it up to 4k etc., 'just' add (aka magic) missing detail into 1080p version and generally unblur it.
Is there anything out there, even in research phase that can take existing video stock, and then hallucinate into it detail that never was there to begin with? What NVidia is demoing here seem like steps to that direction...
I did test out Topaz Video and DaVinci's built-in super resolution feature, both of which gave me a 4k video with some changes to the original. But not the magic I am after.
