GrainFactory3 support for AviSynth ??

[Selur]

Is there a reason it isn't included?

Me not really using Avisynth.
Noboody asking for it to be supported.
My limited free time.
Folks don't add grain that often explitly their content afaik. I usually don't.
I'm not too keen on Avisynth, since it's basically Windows only (there are Linux, MacOS versions, but at least nowadays they are no alternative) and at least to me doesn't offer any gain over Vapoursynth.

I could have sworn it used to be but I could be mistaken.

Nope, I only added it for Vapoursynth. Unless filters are not maintainable I usually don't remove them.

Okay, so question are:

• Since you named three filters: Which one would you like to be added to Hybrid? Not planning to add them all, since it's a pain to add lots of filters with tons of parameters.
  
• Since you noticed that the documentation doesn't seem to be correct:
  Which color spaces (YV8, YV12,YV16,YV24, RGB) and bit depth are (8,10,12,16bit) are really supported by the filters?
  (all paramters need to be tested)
  
• Are the parameters of the filter documented?
  

side note: there are guite a few Avisynth grain filters, see: http://avisynth.nl/index.php/External_filters
