Iirc, many of his early releases were heavily compressed, have no idea if there even is an uncompressed version out there.

Might not be compressed problem, many of his works look just like that and some look like:
You can check kemono page of his gumroad. It has 2019/03-2020/02 collections
AA12 original version is really poor quality, but WA2000 original version is very clear
It's just that most of the versions that people share are compressed or have modified video resolutions
gumroad's 2019.05 original content seems to have been deleted, and kemono on the 2019.05 missing WA2000 lines version
Even the one on Kemono is quite heavily compressed/rendered poorly, with a ton of artifacting when there's a lot of movement.
Edit: I just finished posting the audio file for the voiced version I have then saw that the length of my audio file didn't match up with the length of the video from Kemono. Turns out that the versions I have of WA-2000 are different from the ones there, and were likely edited at some point. The one on Kemono does have lines, they're just all in the second half and synced kinda poorly.

I think I downloaded these ones off Sankaku Channel a few years ago.

all right,Then I'll take this as the original version
I will optimize this video, and then share it with you I used ai to optimize the video image quality and FPS

1080p(Or lower) → 4K (Practical Algorithms for General Image/Video Restoration)

30fps → 60fps (ncnn implementation of RIFE, Real-Time Intermediate Flow Estimation for Video Frame Interpolation)I thought that if the difference between the free version and the paid version is only the quality of the image or the number of frames, and if no one shares the paid version, you can use this method and get a video file of comparable quality to the paid version
Usually the free version released by the artist has 720p or 1080p, and the optimization effect after using the free version is almost not much different from the paid version
However, it should be noted that some artists release paid versions of the content and the free version of the difference, and as an optimization of the video quality as much as possible not too low, because the image quality is too low will lose a lot of detail, ai strictly speaking not in the restoration but in the fantasy picture of the original look. If the image quality is too low the effect will not be ideal (For example AA12 this video)
There are also some artistswho only have 1280*720 or no 60fps version of the video released earlier, using this method, you can create your own higher resolution and 60fps video (For example, つんべじ(tsunbeji)'s long ago work)

Different artist, but could you consider interpolating this one to 60fps as well?

Also, what settings do you use for your upscaling and interpolation, could you send me the bat file or whatever lines you use? I've used a video upscaler that extracted the frames and upscaled it with waifu2x and also ffmpeg's interpolation before, but it doesn't come out anywhere near as smoothly or as consistently as your results.

This txt is an instruction manual
After unzipping the package, first open thisMost settings are default
Here is the crf compression level, 0-50 range, the smaller the value of the file size, the higher the image quality, usually within the range of 18-26 can be
You can select optimization mode here
In order from top to bottom
1:超分辨率 RES (Real-ESRGAN)
2:补帧(Interpolation only without scaling up)
3:超分辨率 RES+补帧 (Real-ESRGAN+Interpolation)
4:超分辨率 CUGAN(This is an image scaling ai model launched by bilibili,The effect is better than Real-ESRGAN, but slower)
5:超分辨率 CUGAN+补帧(CUGAN +Interpolation)
Drag the video to be processed into this area, you can try this test video first,The completed optimized video is in the same file path as the original video
Once you have done the above settings ,click here to start
Note that if the length of the video is 20 minutes or more, you need to set aside 200-600GB of hard disk space (depending on the length of time), if only 1-5 minutes of the range of about 100GB is sufficient
