[HELP] NTSC SD master, best De-Interlace?

[Selur]

I just try to explain that using Deblocker filter on SD file that use 56Mb/s compression is totally useless, because you never see any blocks artifacts with that bitrate.

using a highly artifical example

# Imports
import os
import sys
import ctypes
import vapoursynth as vs
core = vs.core

# Import scripts folder (need to be adjusted)
scriptPath = 'I:/Hybrid/64bit/vsscripts'
sys.path.append(os.path.abspath(scriptPath))

# Loading Support Files  (need to be adjusted)
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/GrainFilter/AdaptiveGrain/adaptivegrain_rs.dll")
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/GrainFilter/AddGrain/AddGrain.dll")
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/ColorFilter/Retinex/Retinex.dll")
import vapoursynth as vs
# getting Vapoursynth core

# Import scripts
import havsfunc

clip = core.std.BlankClip(format=vs.YUV422P8, width=720, height=576, length=1000, color=[128, 128, 128])

# adding grain using GrainFactory3
clip = havsfunc.GrainFactory3(clp=clip)

clip = core.resize.Bicubic(clip=clip, format=vs.YUV444P8, range_s="full")
# color adjustment using Retinex
clip = core.retinex.MSRCP(input=clip, sigma=[25,80,250], fulls=True, fulld=True)
clip = core.resize.Bicubic(clip=clip, format=vs.YUV422P10, range_s="full")

clip.set_output()

compressing it with ProRes, and comparing the encode against the script:

# Imports
import os
import sys
import ctypes
import vapoursynth as vs
core = vs.core

# Import scripts folder (needs to be adjusted)
scriptPath = 'I:/Hybrid/64bit/vsscripts'
sys.path.append(os.path.abspath(scriptPath))

# Loading Support Files (needs to be adjusted)
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/GrainFilter/AdaptiveGrain/adaptivegrain_rs.dll")
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/GrainFilter/AddGrain/AddGrain.dll")
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/ColorFilter/Retinex/Retinex.dll")
core.std.LoadPlugin(path="I:/Hybrid/64bit/vsfilters/SourceFilter/LSmashSource/vslsmashsource.dll")
import vapoursynth as vs
# getting Vapoursynth core

# Import scripts
import havsfunc

clip = core.std.BlankClip(format=vs.YUV422P8, width=720, height=576, length=1000, color=[128, 128, 128])

# adding grain using GrainFactory3
clip = havsfunc.GrainFactory3(clp=clip)


clip = core.resize.Bicubic(clip=clip, format=vs.YUV444P8, range_s="full")
# color adjustment using Retinex
clip = core.retinex.MSRCP(input=clip, sigma=[25,80,250], fulls=True, fulld=True)
clip = core.resize.Bicubic(clip=clip, format=vs.YUV422P10, range_s="full")

# path needs to be adjusted
clip2 = core.lsmas.LibavSMASHSource(source="E:/Output/testing.mov")

difference = core.std.MakeDiff(clip, clip2)
# Output
difference.set_output()

shows quite a few differences,.....

If you want to seriously look into this you should do it in another thread.
