[HELP] Avisynth - DeSpot question

[Selur]

Looking at the used Avisynth script:

ClearAutoloadDirs()
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
LoadPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\LSMASHSource.dll")
LoadPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\RgTools.dll")
LoadPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\masktools2.dll")
LoadPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\mvtools2.dll")
LoadPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\nnedi3.dll")
LoadPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\TIVTC.dll")
LoadPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\Average.dll")
LoadPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\GRunT.dll")
LoadPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\MedianBlur2.dll")
LoadPlugin("C:\Program Files\Hybrid\32bit\avisynthPlugins\despot.dll")
Import("C:\Program Files\Hybrid\32bit\avisynthPlugins\mtmodes.avsi")
Import("C:\Program Files\Hybrid\32bit\avisynthPlugins\QTGMC.avsi")
Import("C:\Program Files\Hybrid\32bit\avisynthPlugins\Zs_RF_Shared.avsi")
Import("C:\Program Files\Hybrid\32bit\avisynthPlugins\Srestore.avsi")

There should be no interlacing.
The encoding call:

ffmpeg_32 -y -noautorotate -nostdin -threads 8 -i "M:\Tanya-TEMP\encodingTempSynthSkript_2023-10-17@17_38_47_8410_0.avs" -an -sn -vf  scale=in_range=tv:out_range=tv -pix_fmt yuv422p10le -strict -1 -vsync 0  -vcodec prores_ks -profile:v 2 -vtag apcn -metadata encoding_tool="Hybrid 2023.10.17.1" -aspect 768:576 -f mov "M:\Tanya-TEMP\Apocalypse Sexual_SpainVH-ACEtbc_1_2023-10-17@17_38_47_8410_04.mov"

looks fine too. (Will look at why the '#output ...'-comment shows the wrong info in the Avisynth script tomorrow, this is just a comment and won't change anything.)

Trying to reproduce this with:

ClearAutoloadDirs()
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
LoadPlugin("F:\Hybrid\32bit\avisynthPlugins\DGDecode.dll")
LoadPlugin("F:\Hybrid\32bit\avisynthPlugins\RgTools.dll")
LoadPlugin("F:\Hybrid\32bit\avisynthPlugins\masktools2.dll")
LoadPlugin("F:\Hybrid\32bit\avisynthPlugins\mvtools2.dll")
LoadPlugin("F:\Hybrid\32bit\avisynthPlugins\nnedi3.dll")
LoadPlugin("F:\Hybrid\32bit\avisynthPlugins\TIVTC.dll")
LoadPlugin("F:\Hybrid\32bit\avisynthPlugins\Average.dll")
LoadPlugin("F:\Hybrid\32bit\avisynthPlugins\GRunT.dll")
LoadPlugin("F:\Hybrid\32bit\avisynthPlugins\MedianBlur2.dll")
LoadPlugin("F:\Hybrid\32bit\avisynthPlugins\despot.dll")
Import("F:\Hybrid\32bit\avisynthPlugins\mtmodes.avsi")
Import("F:\Hybrid\32bit\avisynthPlugins\QTGMC.avsi")
Import("F:\Hybrid\32bit\avisynthPlugins\Zs_RF_Shared.avsi")
Import("F:\Hybrid\32bit\avisynthPlugins\Srestore.avsi")

#  output: color sampling YV12@10, matrix: bt601, scantyp: progressive, luminance scale: limited
return last

and

ffmpeg_32 -r 25/1 -y -noautorotate -nostdin -threads 8 -i "J:\tmp\2023-10-17@20_31_59_4410\encodingTempSynthSkript_2023-10-17@20_31_59_4410_0.avs" -an -sn -vf zscale=rangein=tv:range=tv -pix_fmt yuv422p10le -strict -1 -vsync 0  -vcodec prores_ks -profile:v 2 -vtag apcn -metadata encoding_tool="Hybrid 2023.10.17.1" -aspect 20:15 -f mov "G:\Output\bff_1_2023-10-17@20_31_59_4410_03.mov"

My output is deinterlaced.

If you can share a short sample of your video (which allows reproducing this for you), I can try to look into this some more tomorrow.
(maybe it's something in the source triggering this and thus I can't reproduce it here.)
