[HELP] Suggested filters requested to remove laser rot on LaserDisc of COMMUNION

[Selur]

Looking at sample 1:
a. source was resized and probably sharpened during capturing :/ (not sure the aspect ratio is quite right, but I ignore that)
b. source is not progressive but probably field shifted (this capturing setting were bad)
c. it has tons of noise
had a quick look at sample 2, has similar issues.

What I would start with:

• overwrite the input scan type to 'field shifted' (this will cause Hybrid ot use TFM)
  
• use QTGMC as denoiser for with input type 2 <- will remove residual combing after the field matching.
  
• use Composite for rainbow removal
  
• use SpotLess with Temporal Radius 2 <- this is for the 'sparks'
  
• Crop the black bars
  

then I would enable Retinex to better see the problems and look at denoising, dehalo, color adjustments,... maybe some stabilization (i.e. Temporalfix),...
not really tuned: https://pastebin.com/mpCp2ia2

You could also add something like DetailSharpen (but then Composite refine should be used with 0 to avoid too much sharpening), which I would then move before Spotless. There seems to be a slight chroma shift (x=1.25)




Assuming the capture is as good as you can manage, the above should give some ideas, but you should decide how much denoising&co you want,.. there are tons of screws and fitlers you can try.
