To add to this it’s best to think of upscaling as cooking, if you have an bad set of ingredients and kitchen stuff then you’ll struggle to put out something really good quality wise compared to if you had fresh and good quality ingredients along with the best kitchen gear around.
So if an video is blurry or pixelly…upscaling that will just mean that you end up with the same thing give or take but now in 4k rather than 480p. Hence why it’s best to get the source video or close as possible as the upscaling AI won’t be an magic tool to change it for the better.
Problem is since it’s Texas Presley most of her videos are DVD/CD so expecting their quality to be any better than 720p is next to 0, same as with actually finding it since I doubt that the video’s current name is accurate. As also videos that old that they rarely got put up onto the internet making such old videos be extremely rare and preservation even worse due to time passing.
