lets see... You need to find a method that AI does not mess up long-distance scenes, just an observation to improve your upscales in the future.
I know, thats the problem in Ai Upscale, is very dificult to get that, because the source is not the best, its almost imposible to get, at least in my upscale the imagen dont look like a gosh, like in some upscale happen. Try to upscale from 648x480 to 3840x2160. do you know any upscale method to get a better quality in long distance scenes? That you can share with me. Greetings!
