I'm curious - what's the best open-source video upscaling library out there? I looked back about a year ago, and it didn't seem like there were any good open-source solutions.

An HN search of ''Deep Space Nine'' and ''Topaz'' will show some great discussions here covering the dearth of such upscaling solutions, as well as some huge efforts before commonplace AI.

  I found this single discussion? https://news.ycombinator.com/item?id=19453745 https://news.ycombinator.com/item?id=19453745 And that's by avoiding the word "topaz", where I see no story results with discussions and not much of comment results.

    I can help (I added ''remaster''): https://hn.algolia.com/?dateRange=all&page=0&prefix=true&query=%22Deep%20Space%20Nine%22%20Remaster&sort=byPopularity&type=story https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que... Links to the artciles found in those discussions are to some very enlightening efforts by Joel Hruska to find an upscaling solution related to what the person asked about. As somebody else mentioned, Topaz is out there and Hruska gave it a good shot, but it is not open source.

      Right, I did find those, but only one had a discussion. Just making sure I'm not missing anything, so thanks for the clarification.

Topaz is light years ahead of any open source solution unfortunately.

It depends on what do you mean by 'open-source', along with training materials and full setup? That will be hard to find. Upscaling was popular like 10 years back. That's why there is no much interest today. Training in old style isn't that hard. But artifacts are popping up in all videos I've seen.

It's not exactly what you're after, as it's anime specific and you need to process the video yourself (eg disassemble to frames, run the upscaler, then assemble back to a movie file), but Real-ESRGAN is very good for cleaning up old, low resolution anime: https://github.com/xinntao/Real-ESRGAN/ https://github.com/xinntao/Real-ESRGAN/

  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. https://github.com/bloc97/Anime4K https://github.com/bloc97/Anime4K

    Thanks, hadn't come across that before. :)
