SMDegrain (AviSynth) PreFilter Issue

[phazer11]

1. you can copy the content of those popups using 'CTRL+C', so no need for tons of screenshots.
2. since you didn't post a debug output: What does the used avisynth script look like? I thought that SMDegrain needed removegrain onel when contrasharp as set to true or something other than '0', but seems like I overlooked a call path.

Here's the vapoursynth script which works.

Here's the Avisynth which does not work (even without the other filters) same settings in the GUI
