btw. for those interested I adjusted the scripts over at
https://github.com/Selur/VapoursynthScriptsInHybrid to only use eedi3m and znedi3 when they are available and use the default eedi3 and nnedi3 otherwise, so they should work fine with the installer.
simply place them into your '/Library/Frameworks/VapourSynth.framework/lib/python3.6/site-packages/' folder
