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

[Adamcarter]

Happy you have a use for Hybrid, even when the mac version hasn't got any code changes and updates for 2+ years.

Cu Selur

I don't need changes, although,
docker is becoming very popular. there are ways to make a thin docker container with a thin install of windows (maximum compatibility with vapoursynth and avisynth) could also be made with a thin linux os.
then the docker apps could be loaded on any system (basically a sandboxed application)

I talk as if I know how to do this stuff but I don’t.. or else I would make one.

so interesting issue. when I run qtgmc on vapoursynth with medium setting it works.

when I drop the setting in qtgmc from medium to slow, slower, or very slow, placebo, or custom. that's when I get a crash because the byte size is too small error,

this is my script for medium which works, will try slow script as comparison.

# making sure frame rate is set to 30000/1001
clip = core.std.AssumeFPS(clip, fpsnum=30000, fpsden=1001)
# Setting color range to TV (limited) range.
clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1)

clip = core.std.SetFrameProp(clip=clip, prop="_FieldBased", intval=2)
# Deinterlacing using QTGMC
clip = havsfunc.QTGMC(Input=clip, Preset="Medium", TFF=True)
# Output
clip.set_output()

my very slow script
