Glithes on the preview and in the destination file

enable 'Disable MT' for this source

How much can slow down processing by enabling this option?

You could also try whether using the 64bit version from https://github.com/sorayuki/ColorMatrix/...s/tag/v2.6 helps

I downloaded from this link "colormatrix.dll". This file is identical to the file "c:\Program Files\Hybrid\32bit\avisynthPlugins\ColorMatrix.dll"

I need to replace "c:\Program Files\Hybrid\64bit\Avisynth\avisynthPlugins\ColorMatrix64.dll" ?
Where can I get this file?
