this is what happens on final result using MCdegrainsharp and QTGCM deinterlace.. on the original footage is not too much visible but after the degrain is very very evident.

[Image: defect.jpg]

original footage: https://www.wcn.it/defect.zip

the problem seems related to some sort of fast interference (generated on the TBC) and red seems more influenced from it. the strange thing is that just on this tape is very very evident.

very thnak you for any help!

Looks like some kind of aliasing.
1rst idea try:
1. denoising the separate fields before deinterlacing/ivtc.
2. applying Santiag with increased strength afterward.
will look at it after work.

Here's what that first idea does:
# converting interlaced to half-height progressive for filtering (vsMCTemporalDenoise) (separate fields)
clip = core.resize.Bicubic(clip=clip, format=vs.YUV444P8, range_s="limited")
clip = core.std.SeparateFields(clip, tff=False)
clipEven = clip[::2] # resolution 720x288
clipEven = core.std.SetFrameProps(clip=clipEven, _FieldBased=vs.FIELD_PROGRESSIVE) # progressive
clipOdd = clip[1::2] # resolution 720x288
clipOdd = core.std.SetFrameProps(clip=clipOdd, _FieldBased=vs.FIELD_PROGRESSIVE) # progressive
# denoising using MCTemporalDenoise
clipEven = denoise.MCTemporalDenoise(i=clipEven, settings="very high", ncpu=10)
# denoising using MCTemporalDenoise
clipOdd = denoise.MCTemporalDenoise(i=clipOdd, settings="very high", ncpu=10)
# converting half-height progressive to interlacedbefore deinterlacing
clip = core.std.Interleave([clipOdd, clipEven])
clip = core.std.DoubleWeave(clip=clip, tff=False)  # resolution 720x576
clip = core.std.SelectEvery(clip, 2, 0)
clip = core.std.SetFrameProps(clip=clip, _FieldBased=vs.FIELD_TOP) # tff
# Deinterlacing using TIVTC
clip = core.tivtc.TFM(clip=clip, chroma=True)
clip = core.tivtc.TDecimate(clip=clip, mode=7, rate=23.9760, dupThresh=0.04, vidThresh=3.50, sceneThresh=15.00)# new fps: 23.976
# Making sure content is preceived as frame based
clip = core.std.SetFrameProps(clip=clip, _FieldBased=vs.FIELD_PROGRESSIVE) # progressive
# applying anti aliasing using santiag
clip = antiAliasing.santiag(c=clip, strh=3, strv=3, nns=2, qual=2, pscrn=2, opencl=True)
[Image: grafik.png]
clip

2nd idea: using SpotLess before the deinterlacing and BasicVSR++ on the edges after Santiag. (script,clip)
3rd idea: adding CodeFormer to before BasicVSR++ (script,clip)

Hope these help to get it started. Smile

impressive result!, very very thank you for your time and your help Selur!

just tried the first script:

Failed to evaluate the script:

and i think the "6" need to be removed

but after:

Are you sure you are using the latest dev?
=> please create a debug output, since I can't reproduce this here.
for me scripts like:
# Imports

# getting Vapoursynth core
import ctypes
import sys
import os
core = vs.core
# Import scripts folder
scriptPath = 'F:/Hybrid/64bit/vsscripts'
sys.path.insert(0, os.path.abspath(scriptPath))
# Loading Support Files
Dllref = ctypes.windll.LoadLibrary("F:/Hybrid/64bit/vsfilters/Support/libfftw3f-3.dll")
# loading plugins

# set output frame rate to 25fps (progressive)
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# output
clip.set_output()
get generated and work fine.

sorry for the late reply Selur Sad
here the debug log .. i just installed the latest dev version deleting any folder present before

http://www.wcn.it/debug2025.zip

the preview is showing the same thing.

maybe i'm doing something wrong..

i place the clip.. select the output as MKV, add the audio track... set the quantization to 12 (constant 1 pass)

open CUSTOM tab (vapoursynth)

select "INSERT BEFORE END"

added the code.

Okay, no wonder that isn't working!
Your script is:

  # denoising using MCTemporalDenoise
  clipOdd = denoise.MCTemporalDenoise(i=clipOdd, settings="very high", ncpu=10)
  # converting half-height progressive to interlacedbefore deinterlacing

In your custom section you use:
'denoise','tivtc','antiAliasing' but you don't import the used scripts, or load the required plugins.

No clue why you are using a custom section, to begin with.
The stuff I did in post #3, you can archive by:
  • loading your source
  • enabling and settings 'Filtering->(De-)Interlace/Telecine->Overwrite input scan type to' to 'telecine'
  • setting 'Filtering->(De-)Interlace/Telecine->TIVTC Settings->TDecimate->Mode' to '7'
  • setting 'Filtering->(De-)Interlace/Telecine->TIVTC Settings->TDecimate->Rate' to '23.976'
  • setting 'Filtering->Vapoursynth->Misc->Script->Filter interlace handling' to 'separate fields'
  • enabling 'Filtering->Vapoursynth->DeNoise->MC Temporal Denoise'
  • setting 'Filtering->Vapoursynth->DeNoise->MC Temporal Denoise->Settings' to 'very high' (optionall increasing ncpu to 10)
  • switching to 'Filtering->Vapoursynth->Misc->Filter Order/Queue' and moving 'MCTemporalDenois' above 'Deinterlace'
  • enabling 'Filtering->Vapoursynth->Line->AntiAliasing->Santiag'
  • setting 'Filtering->Vapoursynth->Line->AntiAliasing->Santiag->strength->h&v' both to '3 (optionally enabling 'OpenCL')
For me, the Vapoursynth Script Preview then shows:

In theory, you could use a custom section, but when using a custom section you are responsible to load all dependencies&co.
