Good morning/afternoon/evening, gentlemen.
I want to make a good DVDRip of my MusicDVD collection, everything is ok except I lose the vividness of colors.
I use the following scheme:
Demux VOB to m2v -> Create d2v file -> Create Avisynth script -> Load it to MeGUI and encode using HQ-Slow profile.
The quality is almost lossless, but I have obvious shift in colors, the colors lose their vivdness.
As far as I understand, that is because of YUV-RGB convertion and I should use ColorMatrix plugin to avoid colorshifting. The problem is that I use colormatrix during the creation of Avisynth script in "Avisynth script creator" in MeGUI, but it doesnt look to take any effect.
Here is my script:
DGDecode_mpeg2source("D:\VTS_02_0_cut.d2v",info=3)
ColorMatrix(hints=true,interlaced=true)
Load_Stdcall_Plugin("C:\Program Files\megui\tools\yadif\yadif.dll")
Yadif(order=1)
crop( 24, 8, -8, -8)
#resize
#denoise
GSpot doesnt give any information about color coefficients, as far as I understand it means that they are Rec.709 by default . Colormatrix should convert Rec.709 to Rec.601, but shift in colors still remains. Looks like I use ColorMatrix in a wrong way.
Here is screenshotes of my DVD and DVDRip:
