I have recently come across several / nearly all of the original Sailor Moon DVD releases. I'm assuming it would work ripping these, and running them through an up-scaler just as anything else? Or, would I need to find another source file that would be better quality than the NA DVD release?
For sure, you cannot use the North American release, it is not even remastered version. Even the original Japanese DVDs are quite bad. The best source are the Italian DVDs.

Not necessarily. I use artificial intelligence software to do the upscaling and I found that at Dynit there is a problem. The best source for good AI upscaling will remain Japanese DVDs.

Region 1 (Pioneer)




Region 2 (Japan)





At Dynit, the grain has a problem. This causes a processing problem in the image. To believe that the grain has been added digitally and that it is not the original grain.

Because for example I want to erase all the grain in Dynit, I have to push a plugin to the limit, while the basic settings remove all grain in any work.

The comparison looks fraud to me. I don't recall the Toei remaster having blown out skin color. And the AI upscale quality seems no difference to me.
The colors of the japanese blu ray indeed looked altered, especially on episode 25. The episode is yellowish indeed but not to the extend of the shown footage. Their color correction is decent, but it is a bit deceiving. Btw this is how the blu ray actually looks like and a quick attempt for upscaling and color correction.

Upscaling a video is very easy. You just need to install a few stuff. And copy/paste a command that will use a model on the frames of the video. Then you just have to wait the end of the process.
The problem is that my hardware is not good enough to upscale a video. My gpu is REALLY bad

The reason I posted my results here is to ask for help. If a lot of people are willing to help the whole series can be done quickly whereas it would take more than forever for one person. I'll share the model and then people will just have use it on the Dynit DVD Remux. There is no need for special skills, just a good gpu

I don't want to go too much into the technical aspect but this model was mostly a "proof of concept". I wanted to see if I could get good results with esrgan. The model I trained is slow, I don't think it's realistic to use it for a project aiming at upscaling 200 episodes. That's why I plan to use the results of this slow model to make a much faster model (the quality would be a bit lower but the speed difference is huge)

This AI upscale result looks amazing. Lines are sharp with no halo or ringing. It even kept the imperfection of the lineart intact. Have you tested it on fast motion scenes? Are there any failed attempts on your test samples?

And regarding using the Dynit DVD as source, be informed that the way they handle tape marks on scene change frames are different from Japan. With Toei's blu-ray, they were manually removing them by hand, while Dynit just ran a script to replace those frames with their previous/next frame. So on scenes like a panning shots where every frames is different, the Dynit version will lost the first frame of the scene.

I guess Toei wants it to be treated as though it was one of their digitally made anime.

Toei: Sailor Moon wasn't made on film! it was made in ummm... Pre-release RETAS, yeah, RETAS

I guess it would also explain the next scene peeking from Viz's first versions of many episodes.


as for Dynit Remuxes, which specific one? and what kind of PC specs will we need to aid in this upscale?

I can help, my PC should be able to handle it. Please PM me.

I tested it on fast scene frames (not video) and the results were good.
I need to do more testing but so far the model produces good results on most frames. There is some problems that can be solved by making changes in the dataset and training more.
The details have disappeared in the bluray version so the results with those will be much worse. A capture of the laserdisc might be the best source. We would have to see if it does not contain any blending

Dynit remuxes from the most popular anime tracker (meow in japanese)
I have 2gb of VRAM. It can upscale but it crashes after upscaling a few frames. I guess at least 6 or 8gb of VRAM would be the minimum for this kind of project.
It is also possible to use Google gpu's with Google Collab. They provide a pretty good gpu for 3 hours every 24 hours for free users. That's how I was able to train the model. But I don't think 3h is enough to do a whole episode.

What I was saying is that Toei did a better job than the Dynit, they actually fixed the frames instead of replacing them with another one.
