[GUIDE] VapourSynth + QTGMC Deinterlace + Hybrid UI FAQ for macOS

Ok, i can contact timecube developer about this problem, but i notice that there is no black screen if i use format=vs.RGB24 instead of format=vs.RGB48, and manually run in vsViever

import vapoursynth as vs
core = vs.get_core()
clip = core.lsmas.LibavSMASHSource(source="/Users/shph/Desktop/44.1hz test source.mov")
clip = core.resize.Point(clip, matrix_in_s="709",range_s="limited")
clip = core.std.AssumeFPS(clip, fpsnum=25, fpsden=1)
clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1)
clip = core.resize.Bicubic(clip=clip, matrix_in_s="470bg", matrix_s="709", range_in=0, range=0)
clip = core.resize.Bicubic(clip=clip, [b]format=vs.RGB24[/b], matrix_in_s="709", range_s="limited")
clip = core.timecube.Cube(clip=clip, cube="/Applications/Hybrid.app/Contents/MacOS/TimeCubeFiles/identity.cube")
clip = core.std.Levels(clip=clip, min_in=16, max_in=235, min_out=16, max_out=235)
clip = core.resize.Bicubic(clip=clip, format=vs.YUV422P10, matrix_s="709", range_s="limited")
clip.set_output()

Also if i import 10 bit ProRes source and use Levels filter (TimeCube turned OFF) i see a green overlay artifact in vsViewer preview.

If i import 8 bit source and use Levels filter image looks OK if Gamma set to 1.00.
But when i start to adjust Gamma, i start to see green overlay artifact in vsViewer preview.

So i guess it more looks like bug in Hybrid bit depth-color management code with some filters.
