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

[Selur]

but i can't see any error messages in Hybrid when use it.

Check the Vaporusynth Script View to be sure it's used.
Also when using the Filter View it should be easy to spot whether dpid works or not when down-scaling a lot (here 4k to sd):

So i guess it is some namespace problem somewhere between these filters.

What makes you thing that?
With sangnom.SangNom and sangnom.SangNomMod the collision is since they both use the same namespace 'sangnom'.

Using both filters, works fine in Windows:

# Imports
import vapoursynth as vs
# getting Vapoursynth core
core = vs.core
# Loading Plugins
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/ResizeFilter/DPID/vapoursynth-dpid.dll")
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/Support/fmtconv.dll")
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/DerainbowFilter/DeCross/libdecross.dll")
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/SourceFilter/DGDecNV/DGDecodeNV.dll")

# Loading G:\TestClips&Co\files\MPEG-4 H.264\4k\4k_sample_4096x2160.mp4 using DGSource
clip = core.dgdecodenv.DGSource("E:/Temp/mp4_b30946f06bbf6d3e0309b51cccf4cf0c_853323747.dgi")
# making sure input color matrix is set as 2020cl
clip = core.resize.Point(clip, matrix_in_s="2020cl",range_s="limited")
# making sure frame rate is set to 25
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# Setting color range to TV (limited) range.
clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1)
# rainbow removal using DeCross
clip = core.decross.DeCross(clip=clip)
# Resizing: 4096x2160 -> 720x380
clip = core.dpid.Dpid(clip=clip, width=720, height=380, read_chromaloc=True)
# adjusting output color from: YUV420P8 to YUV420P10 for x265Model (i420@8)
clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P10, range_s="limited")
# set output frame rate to 25.000fps
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# Output
clip.set_output()

So I doubt it's a namespace problem.
I also don't see where 'decross.DeCross(' and 'dpid.Dpid(' would overlap), or I simply don't understand what you understand as 'some namespace problem'.
