Need help removing heavy analog artifacts from this source

[themon-master]

Hello! I'm trying to restore this source and I'm struggling trying to remove the rainbow & dotcrawl artifacts (a.k.a analog artifacts)

Can anyone help me out here? thank you!

have you tried:

• descale
• some anti-aliasing
• QTGMC inputtype=3 + some derainbow filters (RainbowSmooth, SRFComb2, BiFrost)

that is the first that pops up in my mind,...

I tried these before but they didn't help with anything, I tried to descale (to 540p) and anti-aliasing using NNEDI3_rpow2, it doesn't help with the analog artifacts.

For some of the derainbow filters I tried leaves out a chroma issue that wasn't in the original source (I am using the default script, so it could be fixed)
(I tried this on, BiFrost, DeDot, and TComb)

I couldn't find any scripts that fully fixes the dotcrawl issue, but the best I got was QTGMC + DotKillS

Are you using Avisynth? Maybe you can try ChubbyRain2 for rainbows and Checkmate for dot crawl

ChubbyRain2 + Decross has been working well for me at de-rainbowing while not making the original colors muted in the process.

Just for fun,.. (script)

Yikes, this filtering looks terrible

All I needed was the rainbowing and dotcrawl to be removed, I can script the rest myself.

Decided to test out the filters you recommended to me, ChubbyRain2 & Decross doesn't help me at all, it's still giving me that chroma issue I mentioned earlier, I have no idea why all these derainbow filters give me that issue, this never happens on any other source I test this out with and it's driving me crazy.
Checkmate on the other hand actually helped with the dotcrawl removal, but I can't seem to hit the "sweetspot" on the script because some frames the dotcrawl is removed, but other frames the dotcrawl is there.

then try:
RainbowSmooth(radius=7, lthresh=50)
to remove rainbows. + some line darkening filter

For the dot crawlers you probably need to use different setting per scene, the running scene otherwise ends up with artifacts like you spotted above.
(or use some machine learning based filter)

RainbowSmooth(radius=7, lthresh=50)

Wow, it looks like RainbowSmooth helps a lot but isn't RainbowSmooth 32-bit? I need a 64-bit version of the plugin since I only use the the 64-bit version of AviSynth.

or use some machine learning based filter

I thought of using mlrt_ncnn but the problem is that it won't install on StaxRip correctly, I install both mlrt_ncnn.dll and mlrt.avsi files on the
StaxRip -> Settings -> Plugins -> AviSynth folder, I use the script

mlrt_ncnn(network_path="1x_Dotzilla_Compact_80k_net_g.onnx", builtin=false)

but it gives me an error saying "expects clip with type fp32", so I added "fp16=true" after the "builtin=false" command, but it gives me the same error, idk what the problem is and I'd like to use this plugin on other sources

[Selur]

Never really used StaxRip, but the error message seems to be clear.
Also looking https://github.com/Asd-g/avs-mlrt/blob/main/mlrt_ncnn/README.md

• input
  Clips to process.
  They must be in RGB/Gray 32-bit planar format, have same dimensions and same number of frames.

so you need to use:

ConvertBits(32)
ConvertToPlanarRGB()

before your mlrt_ncnn call.
see: https://forum.doom9.org/showthread.php?t=184768
Note that: you might have to add an additional color conversion, since anther filters might not support 32bit RGB als input.

Oh, that was the problem, I didn't thought of that, it's fixed now, but I do I revert the converts after I used the plugin? I know to revert the bits which is "ConvertBits(8)" command, but what about the "ConvertToPlanarRGB()" command?, I can't figure out a way to revert that

[Selur]

Whether you want to revert the conversion is up to you and your needs.
guessing your format was before YUV420P8
your can use:

ConvertToYUV420()   # see: http://avisynth.nl/index.php/Convert
ConvertBits(8)
