I know, nobody wants to hear, but…
You are right. Those details don’t exist but I don’t think anyone expects it to be as good as a human restorer.
I tested the new app and I am amazed by the results. It’s even better than the Beta app.
I’m also not 100% sure if Gigapixel checks for similar patterns or objects already registered, but by what’s available on the picture itself and sort of digital painting new pixels. but I don’t know. I’m just observing the process and comparing.
I will post a side by side picture of the upscaling results for my Beauty and the Beast LD for comparison. I was so skeptical, but what I see is more than I hoped for. To me it’s still better than some of the terrible restoration done by the humans at Disney mostly because of certain decisions they made to alter the original. 😃
