[HELP] Avisynth - DeSpot question

[Miranda]

I converted the DV file to ProRes and AviSynth worked perfectly. Strange.

DV to ProRes coversion, MediaInfo:

Scan type: Interlaced
Original scan type: Progressive
Scan type, store method: Interleaved fields
Scan order: Bottom Field First

I'm confused about these settings. What is an outlier? Can it include simple dropouts/line flashes as seen on old videotapes?

Set mode for removing of only black or white spots or both:

• sign = 0 - any spots and outliers (default)
  
• sign = 1 - only black (dark) spots and outliers
  
• sign = -1 - only white (light) spots and outliers
  
• sign = 2 - only black (dark) spots, any outliers
  
• sign = -2 - only white (light) spots, any outliers

For lines large scratches, DeScratch and maybe Spotless are usually more suited. (sadly there is no port of DeScratch for Vapoursynth)
Read "HOW IT WORKS" over at http://www.avisynth.nl/users/fizick/despot/despot.html to get a better understanding of DeSpot.

It's varying sizes of horizontal lines I need to remove, so I doubt DeScratch would work.

Depending on the source, you would need to use a custom section and then use multiple descratch calls with different settings.
So it might be worth a try, but could also not help.
