Fields-shifted Video - richtiges "Decombing"

[Selur]

Das von Dir gepostete Skript zeigt:

# Current color space: YUV420P8, bit depth: 8, resolution: 1920x1080, frame rate: 25fps, scanorder: progressive, yuv luminance scale: limited, matrix: 709, format: mpeg-2

Aber wenn ich die sample.ts hier lade sehe ich:

# Current color space: YUV420P8, bit depth: 8, resolution: 1920x1080, frame rate: 25fps, scanorder: bottom field first, yuv luminance scale: limited, matrix: 709, format: mpeg-2

Bei mir wird wenn ich TFM aktiviere:

# Imports
import vapoursynth as vs
# getting Vapoursynth core
import sys
import os
core = vs.core
# Limit frame cache to 48449MB
core.max_cache_size = 48449
# Import scripts folder
scriptPath = 'F:/Hybrid/64bit/vsscripts'
sys.path.insert(0, os.path.abspath(scriptPath))
# loading plugins
core.std.LoadPlugin(path="F:/Hybrid/64bit/vsfilters/Support/fmtconv.dll")

# Import scripts

clip = core.dgdecodenv.DGSource("J:/tmp/ts_3591dab47f54c59fc132a441faa50717_853323747.dgi",fieldop=0)# 25 fps, scanorder: bottom field first
frame = clip.get_frame(0)
# setting color matrix to 709.
clip = core.std.SetFrameProps(clip, _Matrix=vs.MATRIX_BT709)
# setting color transfer (vs.TRANSFER_BT709), if it is not set.
if validate.transferIsInvalid(clip):
  clip = core.std.SetFrameProps(clip=clip, _Transfer=vs.TRANSFER_BT709)
# setting color primaries info (to vs.PRIMARIES_BT709), if it is not set.
if validate.primariesIsInvalid(clip):
  clip = core.std.SetFrameProps(clip=clip, _Primaries=vs.PRIMARIES_BT709)
# setting color range to TV (limited) range.
clip = core.std.SetFrameProps(clip=clip, _ColorRange=vs.RANGE_LIMITED)
# making sure frame rate is set to 25fps
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# making sure the detected scan type is set (detected: bottom field first)
clip = core.std.SetFrameProps(clip=clip, _FieldBased=vs.FIELD_BOTTOM) # bff
clip = core.tivtc.TFM(clip)
# Making sure content is preceived as frame based
clip = core.std.SetFrameProps(clip=clip, _FieldBased=vs.FIELD_PROGRESSIVE) # progressive
# no resizing since resolution is already archived
# adjusting output color from: YUV420P8 to YUV420P10 for NVEncModel
clip = core.resize.Bicubic(clip=clip, format=vs.YUV420P10)
# set output frame rate to 25fps (progressive)
clip = core.std.AssumeFPS(clip=clip, fpsnum=25, fpsden=1)
# output
clip.set_output()

erzeugt. Da sieht alles okay aus.
=> wie gesagt, schau mal ob das Problem mit der aktuellen Version nicht gefixed ist.

------------
Nebenbei:
'Decombing' ist ein anderes Wort für Deinterlacing. Was Du willst "field-matching". Da sind TFM oder VFM die richtigen Filter.
