I'm perplexed by all this "AI Upscaling"
It looks like a daub of paint and brush + sharpening filter and some other filters
It's only good for conditional anime
I work really hard to remove that paint/brush look, but with the quality of the original DVDs, it's a little bit inevitable with the current state of the software I'm finding. Most/if not all the extra sharpening is my choosing, I can opt to not add any additional sharpening, but to my eyes it makes a nicer looking image. It's all a fine line, and I'm always improving my methods, and the software is continually improving. The first set of upscales I did look pretty bad lol, there's a reason I never shared them. There's also a reason I've been collecting all the original ISO/DVD/BR discs; garbage in -> garbage out. That's why my favorite upscales so far have been from BR discs (although I've found the latest BR disc I'm working on is giving me some issues). Certain scenes are certainly a struggle, especially on some of the older DVDs where the quality at parts is quite bad. Getting the AI to cooperate has not always been easy. It might end up turning into breaking each scene out, running through different pre-processing, AI upscale, and post-processing on each scene, and then recombining everything.
Something you might not realize is the software can also do 100% scaling, so it's just denoising/deblocking, deblur/antialias, remove halo artifcasts, sharpen, and more without actually upscaling it. It does a pretty good job without too much hassle. It'll keep the look, and just give you a cleaner video. It also runs at 30FPS, so real-time or 1/2-framerate on 60fps titles on my RTX3080/Ryzen 5800x computer (or less, it's not fully utilizing the PC on low-res videos).
At the end of the day it's all personal preference. That's the reason I'll be uploading the original, because I know some people won't like my version. I very much prefer my versions over the original quality I found on the web, and even the original DVDs.
