Remastered hajime no ippo

[doggo]

So I've been doing some remastering using AI algorithms on an old anime, hajime no ippo, a boxing anime and have just finished it. The type of remastering I did was to enhance the resolution, clean up artifacts/noise, and frame interpolation. I've made my own subreddit, in there I've got more info, as well as some FAQs. Check it out!

For now I'll be doing anime, the next series will be the old hunter x hunter. At some point I want to try out live action content, specifically action stuff like martial arts movies, or straight up action, but for now the interpolation algorithms aren't quite good enough, or well actually they kinda are, at least the high end ones, but good luck trying to interpolate anything with those on anything other than a RTX 3090.

Hey, sounds interesting. I seem to need an account on lbry (not sure I WANT to have an account there) so I'll have to check that out later.

You can watch the soul eater, one punch man fight scene, or the first 3 eps of ippo without making an account.

True, the results are pretty striking ! Funny to see how the ai also intepreted some stuff, mostly in the backgrounds some have rather flat colours in the original, but the remastered version seems to add some painbrush textures on some surfaces for example.

Yeah, there's a model that doesn't add paintbrush strokes to it, but I actually didn't like it as much and thought the addition of this extra "grit" would make it look nicer, so I went with it.
Doesn't work as well with more nu-anime as the style is more "computer painted" which doesn't work as well, or maybe I just gotta mess with the settings a bit more.

If you look real closely, the colours are a tad different too, a slightly different shade. Not sure how I feel about this, but I think I like it. It's due to the AI working in yuv444 format, whilst the originals were 420, and so it does it's best to convert them into 444 which changes it a bit. I viewed these on my TV and found them better as the yuv444 format adds more of a pop to the colours, not quite the same as increasing saturation mind you.
