Fix terrible deinterlacing(?) artifacts - Bluray

So how do I get rid of these?



Since the video metadata is "Top Field First, InterleavedFields, NTSC,...", Im not sure if these are actually deinterlacing artifacts.
Did they upscale without deinterlacing?

I tried qtgmc inputtype=2 but thats obviously not helping alot.
When I think about it, these don't even look that horizontal at all.

Please help

The video is 29.97 fps progressive, it is an unusual frame rate for anime, what is your source?

It's apparently the US bluray of naruto.

Do you think it has been tampered with?

I don't know, but I do have a US release of an older anime on blu-ray that was also 29.97 fps. Apparently they only did the field matching on the video and then called it a day.

For this one I don't think it is fixable, there is no pattern of the problem. Somebody screwed up on the upscaling process.

Probably they were originally dot crawl artifacts that have gone through several generations and upscaled

What a shame. On other frames the upscale doesn't even seem to be that bad.
How are they selling this?!

Thing is, looking at the dvd, I can't even make out these thing would even get generated. Really weird.

EDIT:
The review on blu-ray.com makes it clear that this is indeed the raw video from the disc. Shit

Ui. Interessing that these models were able to tell something's wrong.
Thank you for the comparison.
I can't wait for these to improve even more. BasicVSR completely deforms the trees and the small mountain on the bottom-left .
I'll stick with the DVD's since they also don't have the weird color tint issues.

BasicVSR++ is very impressive when it gets it "right", but awful when it makes a "wrong" decision, usually turn whatever object it misunderstands into either just a smudge or something completely different, which is very unfortunate since it's very good at cleaning up rainbowing and dotcrawl on anime.
I really wish there was a simple way to iterate it's training further.

Using a mask in combination with BasicVSR++ (or DPIR denoise) often helps.

Just to chime in about the source, Naruto is a mixed frame rate show (has 24fps and 30fps content), so that is why the blu-ray is 30fps interlaced. Make sure you account for this when converting by doing variable frame rate.

Oh thanks I didn't know that.
But I've decided to just use the DVD instead.
Do you by any chance know if this is the same case for the DVD?
How do I handle that? Is there a way to dynamically let it choose the framerate.
Season 1 alone has a lot of epsiodes.

It would be the case for the DVD as well as it is how the show was animated then put together. I don't have any good up to date information on creating VFR files, I was just familiar with the source so I figured I would point that out, sorry.

maybe do basicvsr++ combined with some line masks then use your preferred denoising filters on the rest of the image. you can always manipulate your masks to get best result.

after many years of encoding experience i can tell you that such sources are not worth the effort most of the times. DVDs are not guaranteed to be better (could be though) especially that the BD is also interlaced. Could be that they just upscaled the DVDs and put them on the BDs, who knows?
