This is great for entertainment (and hopefully the main application), but we need clear marking of such type of videos before hallucinated details are used as "proofs" of any kind by people not knowing how this works. Software video/photography on smartphones is already using proprietary algorithms that "infer" non-existent or fake details, and this would be at an even bigger scale.
Funny to think of all those scenes in TV and movies when someone would magically "enhance" a low-resolution image to be crystal clear. At the time, nerds scoffed, but now we know they were simply using an AI to super-scale it. In retrospect, how many fictional villains were condemned on the basis of hallucinated evidence? :-D
