[HELP] Ringing, Mosquito or Blocking

[Selur]

Aside from ccd I would definitly try to fix the chroma issues with either a denoiser (in chroma only) or/and some derainbow filtering.
Will look at it later, after Work

From what I can see, the source has some interlacing and noticeable rainbow artifacts. I’ve attached a screenshot for reference. 
I was able to resolve the interlacing using QTGMC and corrected the frame blending (ghosting) with SRestore, but the rainbow artifacts around edges are still present.

[Selur]

try
a. RainbowSmooth
b. HQDN3D with 0 on luma, but increased Chroma filtering. (mainly increase spatial and be careful with increasing temporal)

Things are a bit improved with your suggestions, thanks! It’s still not perfect, though—if you could help me fine-tune it further, that would be amazing. Also, could you share the exact HQDN3D settings you recommend? That would be really helpful.

Will look at it after work.

Okay, neither HQDN3D nor RainbowSmooth will help with those since they are static on single images.
Only way to get rid of those is:
a. writing some custom script
b. using some machine learning filter like BasicVSR++ (maybe there is a model over at https://openmodeldb.info/ could also help)
Problem is, you basically need something that is meant to be 'destructive/creative'.

Hey, thanks a lot for taking the time to help me out and for all the suggestions you gave me. I really appreciate it. Thanks to you, I’ve already managed to improve the render a bit, so I’m genuinely grateful for that.
That said, I don’t think I’ll go down the AI-based route. I’d like to preserve the authenticity of the anime as much as possible, even if that means keeping some of the original imperfections.
By the way, what would you recommend for deinterlacing and ghosting? What do you think is the most effective approach for those?
Thanks again for your help!

[Selur]

there is no best:
1st try to do proper source handling
2nd for telecined contend: TIVTC or QTGMC + sRestore
3nd for interlaced content: QTGMC (+ sRestore if you have blends)
4th anything lese get creative

there is no real removing of ghosts only solution atm. is dropping or replacing frames with ghosts in them.

Alright, got it — thanks! And if I want to use your script, how should I go about it? I’m really bad at this stuff
Like, should I just load it directly into Hybrid or do I need to modify anything first?
Thanks again for your help!
