Avisynth script performance
I have been following this forum for some time, and I have already gained a lot of information for my avisynth script.
I learned a lot from: StainlessS, VideoFred, johnmeyer and many. First of all, thank you for that 
Only now I am looking if I can tune the performace of my avisynth script. I have already applied many of the mentioned tricks, but think that this is not yet the maximum possible. Because currently it is around 3.5fps.
I have already thought about migrating to vaporsynth, only I wonder if that will get the desired speed (8fps minimum).
That is why I hope that people can help here.
The flow: - Down scaling
- Stabilizing/Cropping
- Removedirt
- Gammac correction
- Up scaling
- Sharpen
- Denoising
Note: indeed it is based on the script of videofred and many of the later mentioned improvements. if I harm someone with this script, let me know, I will of course remove it. If I have not given someone a credit, please let me know.
