reversing "overwrite input scan"

[Selur]

If you encoded interlaced content as progressive, you hard-coded the combing artifacts, in case you resized the content vertically you even altered the combing lines.
You will probably have to sacrifice half or more of the horizontal resolution to get rid of these artifacts.

Try:

• loading your source
  
• enable "Crop/Resize->Base->Resize"
  
• enable "Filtering->Vapoursynth->Frame->Resize->Resizer" (and select NNEDI3)
  
• enable "Filtering->Vapoursynth->Misc->Script->Lower res. before resize"
  
• enable "Filtering->Vapoursynth->Misc->Script->Lower res. before resize->Only height"
  
• check the Vaporusynth preview
  
• increase the factor (default 2) until all combing is gone.
  

if that doesn't help create a small sample of your file, share it with me and I might be able to can suggest something else.
