Quote:Do now get a preview of a sorts when loading avs but it is not a filter preview because for example I do not see effect of the Tweak filter.Okay, it is strange that you write that because according to the debug output you posted Hybrid does not use a modified avs file but just the avs file you used as input, thus it should be the other way around.
Encoding the file however works and the change in saturation can be seen in the end result.
Also: You are using the AvisynthPreview right, because inside the normal preview Avisynth is disabled by default,...
-> Please create a debug output of the preview not working / showing the effects of tweak, so I can see what is called, to know whether you are using the wrong preview or whether there is a bug.
