Anime4K VS waifu2x

I watch AI enhanced movies and/or shows every day when I use Anime4K, a real-time ML upscaler for anime https://github.com/bloc97/Anime4K

If you give shit-tier blurry DVD messes, it turns them into nicer blurry messes.

If you give it the usual bitrate starved streaming quality show, it looks almost as nice as a blueray.

If you give it a blueray... It basically comes out looking exactly the same. I'll usually still add its "darken lines" filter since I'm a fan of strong linework.

> Can you explain what mpv offers over vlc ?

People have complained about VLC's decoding quality in the past (no specific source but lots of google results). I'm sure there's valid bugs that have been patched over and some still there, but I'd take it with a grain of salt since VLC is super popular and therefore more noise when it drops the ball.

That said, there's a few MPV-only features I absolutely love. One is that you can display multiple subtitles at once (for learning foreign languages) and another is that you can drop in upscaling / sharpening filters like [1].

If you want to avoid manual processing, Anime4K runs in real time as a GLSL shader you can load into MPV (or Plex or something called IINA according to the readme) and still gives great results.

I came up with some shaders (here) that I want to load on the Android MPV. I copied the shaders in my Android phone. According to what I found, I edited the mpv.conf with the locations of the shaders as below:

Players like VLC do much better and let you make your own arbitrary adjustments via GLSL :)

In particular, I like the anime4k shader pack, which is ML-based but runs in real time in mpv (and I think VLC as well). While it is tuned for anime (as is obvious from the name), it has decent denoise and deblur which often make YT content more watchable and a restore step that does a really good job with compression artifacts but is a bit too tuned for anime so may not always work, or even make things worse. See https://github.com/bloc97/Anime4K/releases

I know of https://github.com/bloc97/Anime4K that can do real-time upscaling of anime.

Anime 4k

You can start with the Anime4k setup guide: https://github.com/bloc97/Anime4K/blob/master/md/GLSL_Instructions_Windows.md

Personally, it's not really any better than mpv filters like NIS [0] (Nvidia Image Scaling, which does not use AI but is somehow more sharp than these filters) as well as Anime4k [1] (which does use AI but only in the training phase to create the initial glsl file which then does not use AI inferencing but plain old image filters).

Combine mpv with its yt-dlp [2] and SponsorBlock support [3] and you have a competent way to upscale your own YouTube (and other types of [4]) videos.

You can export the large PDF as a JPG then resize it using Tools > Adjust Size. You could also use https://waifu2x.udp.jp to "up-size" the smaller file to give it a bit more resolution. You can set up an Automator script to resize multiple images.

Just use waifu2x to make it bigger

Crop it yourself with Gimp (free) or Photoshop (paid), then upscale it with something like Waifu2x.

You can use https://waifu2x.udp.jp/ AI to enhance 2k or 4k. I made a 2k wallpaper.

You can try screenshot it and go to waifu2x to make it bigger
