Pixellation and Distortion after encoding VC-1 material with MeGUI

[MaxPlanck]

I'm trying to backup my collection of blu-ray trilogies, but I can't seem to figure out why I get out of sync audio and pixellation in my output. I'm hardly an expert, but I'll try to provide as much detail as I can about the process I've used. Please don't hesitate to ask for more information as I'm not sure what may or may not be relevant to this particular problem.

Movie: Lord of the Rings: Fellowship of the Ring

Software / Tools I've installed:


MeGUi
AVISynth
Haali Media Splitter
FFDSHOW Tryouts (using libavcodec to decode VC-1)
Windows 7 Preferred Filter Tweak


Steps I've taken to encode the movie:

1.) Used the HD Streams Extractor to extract audio to AC3
2.) Encoded the .AC3 using NeroAAC
3.) I loaded the .m2ts file directly into the AVS Script Creator (didn't index the file). Here is the script that was generated:

DirectShowSource("C:\Users\Mark Fallone\Desktop\LOTR Rip\00001.m2ts", fps=23.976, audio=false, convertfps=true)
#deinterlace
crop( 0, 142, 0, -144)

Spline36Resize(1280,528) # Spline36 (Neutral)
LoadPlugin("C:\Program Files (x86)\MeGUI\tools\avisynth_plugin\UnDot.dll")
Undot() # Minimal Noise


4.) Saved, Loaded the Script into MeGUI and calculated bitrate
5.) Muxed the audio/video into an .MKV container

What am I doing wrong?

As you said, you didn't index the file. You should only use DirectShowSource as a source filter if you have no other options.

yepp...either you index the file with DGINDEXNV or you use FFMS2, which is <nearly> frame accurate. You also can try DSS2 (inside Matroska Package) with matroska splitter installed and a more or less good decoder (CoreAVC recommended).

P.S.: If you have HD Material, i would recommend to use Lanczos4Resize OR Lanczosresize OR Spline64Resize --- Spline36 steals too much detail for my taste...
P.P.S.: I would NOT use undot() anymore - removegrain is far more developed...it exists a HD-Version as well (RemovegrainHD()).
