[HELP] NTSC SD master, best De-Interlace?
#20
Quote: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.
