-> test with the release and create a debug output with that version if it still fails for you
This is what happens with current version for me when I try to reproduce your problem:
Code:
# Imports
import vapoursynth as vs
# getting Vapoursynth core
import sys
import os
core = vs.core
# Import scripts folder
scriptPath = 'F:/workspace/Hybrid/debug/64bit/vsscripts'
sys.path.insert(0, os.path.abspath(scriptPath))
# Loading Plugins
core.std.LoadPlugin(path="F:/workspace/Hybrid/debug/64bit/vsfilters/Support/fmtconv.dll")
core.std.LoadPlugin(path="F:/workspace/Hybrid/debug/64bit/vsfilters/DenoiseFilter/MiniDeen/libminideen.dll")

Okay, then I need a step-by-step of what you are doing, since it must be related to some step changing the outcome.
= same result !
