[HELP] AviSynth 32 bit - ColorMatrix filter not working for video?
#9
Okay, I can reproduce the problem with your sample,...
Works fine with the attached file from me. Smile

-> looking into it Smile

Preview script itself looks fine:
ClearAutoloadDirs()
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
LoadCPlugin("I:\Hybrid\32bit\AVISYN~1\ffms2.dll")
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\ColorMatrix.dll")
# loading source: C:\Users\Selur\Desktop\ColorTest.mp4
#  color sampling YV12@8, matrix: bt709, scantyp: progressive, luminance scale: limited
Source = FFVideoSource("C:\Users\Selur\Desktop\COLORT~1.MP4",cachefile="E:\Temp\mp4_cc56df01aa772a307c11e0e45982b2c1_853323747_1_0.ffindex",colorspace="YV12")
# current resolution: 1440x1080
SourceFiltered = Source
# color modifications
SourceFiltered = SourceFiltered.ColorMatrix(mode="Rec.709->Rec.601",interlaced=false,hints=false)
# filtering
# adjust color to RGB32
SourceFiltered = SourceFiltered.ConvertToRGB32(matrix="Rec601")
# adjust color to RGB32
Source = Source.ConvertToRGB32(matrix="Rec709")
# interleaving for filter preview
Source = Source.Subtitle("Original")
SourceFiltered = SourceFiltered.Subtitle("Filtered")
Interleave(Source, SourceFiltered)
PreFetch(8)
return last
-> no clue atm. why, but I noticed another bug. Clipping lection doesn't change the script :/

Using another source filter doesn't make a difference either.

Cu Selur
Ps.: Opened a post over at doom9s, may be someone else sees the problem.
