[HELP] AviSynth 32 bit - ColorMatrix filter not working for video?

[The_Tinkerer]

SORRY BUT... 

There is still a problem! Hopefully easy to fix...

If I load an image sequence with bt709 selected, like this:



And I do a color matrix to go from 709 -> 601, I get a wrong Avisynth script:



I believe that the highlighted line should read: ConvertToYUY2(interlaced=false, matrix="Rec709")


The Rec601 gives wrong colors.

I tried a custom script and it gives correct colors:

LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\ColorMatrix.dll")
ConvertToYUY2(interlaced=false, matrix="Rec709")
ColorMatrix(mode="Rec.709->Rec.601",clamp=3,interlaced=false,hints=false)

This is all because I'm using Topaz Video Enhance AI and outputting to 8 bit png. For DVD, it shifts the color palette. Using ColorMatrix Rec.709->Rec.601 fixes it. But not when ConvertToYUY2 has matrix set to Rec601.
