  1. Hi guys,

    I have a DVD with following specifications.

    Code:
    Video
    ID                                       : 224 (0xE0)
    Format                                   : MPEG Video
    Format version                           : Version 2
    Format profile                           : Main@Main
    Format settings, BVOP                    : Yes
    Format settings, Matrix                  : Custom
    Format settings, GOP                     : Variable
    Format settings, picture structure       : Frame
    Duration                                 : 35mn 59s
    Bit rate mode                            : Variable
    Maximum bit rate                         : 7 000 Kbps
    Width                                    : 720 pixels
    Height                                   : 576 pixels
    Display aspect ratio                     : 16:9
    Frame rate                               : 25.000 fps
    Standard                                 : PAL
    Color space                              : YUV
    Chroma subsampling                       : 4:2:0
    Bit depth                                : 8 bits
    Scan type                                : Interlaced
    Scan order                               : Top Field First
    Compression mode                         : Lossy
    Time code of first frame                 : 00:00:00:00
    Time code source                         : Group of pictures header
    GOP, Open/Closed                         : Closed
    When I try to encode this DVD to .mkv, framerate falls down to 20.000fps and the audio goes out of sync.

    Source details detected by MeGUI

    M-in-5 decimation required
    Deinterlace : Tritical Decimate

    MeGUI Version : 2525

    Script

    Code:
    LoadPlugin("E:\Apps\MeGUI_2525_x86\tools\dgindex\DGDecode.dll")
    DGDecode_mpeg2source("E:\Downloads\Kaaki Sattai [2015]\VIDEO_TS\VTS_03_1.d2v", cpu=4, info=3)
    LoadPlugin("E:\Apps\MeGUI_2525_x86\tools\avisynth_plugin\ColorMatrix.dll")
    ColorMatrix(hints=true, interlaced=true, threads=0)
    LoadPlugin("E:\Apps\MeGUI_2525_x86\tools\avisynth_plugin\TIVTC.dll")
    TDecimate(cycleR=1)
    Is there anyway to fix it?

    Yes, remove the TDecimate line from your script.

    At least that will return it to 25fps. The audio shouldn't go out of synch, though, just by removing one frame in five.

    That line was automatically added by MeGUI after analysing the source.

    Yes, it'll improve the quality because it won't play jerky afterwards.

    Meaning what? That it has to be right? Hardly. You could always post a short sample for someone to have a look. Eyes are always better than an automatic analysis anyway. 10 seconds of steady motion will be plenty. You can use DGIndex to cut out a small M2V from the DVD. I believe MeGUI uses DGIndex so you should have it already.

    I am sorry to say that I have never used DGIndex to split a video.

    VTS_03_1.d2v of the DVD, if this can help in any manner.

    No, useless. All PAL D2Vs have the same things inside.

    To cut a piece of a VOB, open it in DGIndex. Use the slider and the [ and ] buttons to isolate a small section. Then go File->Save Project and Demux Video. Upload the resulting M2V here. Again, 10 seconds or so with steady motion will be plenty.

    But, as I said before, removing the line from the script will fix the framerate problem. I don't know whether or not it'll fix the out-of-synch audio.

    Here you go mate : Sample

  8. Oh, it's Indian. Then all bets are off. It was converted from film to PAL (24fps->25fps) by the idiotic method of adding one duplicate frame every second. So it has a slight stutter or jerk every second, most easily seen during certain kinds of slow movement. So, replace that TDecimate line in the script with this:

    TDecimate(Mode=0,Cycle=25,CycleR=1)

    That will remove the duplicate frames and bring it to 24fps. The length remains the same so nothing has to be done with the audio. It seems I saw one of these just the other day. So there's some South Indian DVD company that thinks doing it this way is a good idea? Well, it's better than field-blending, I suppose, and it can be fixed fairly painlessly.

  9. Frame rate issue is fixed, but still there is an audio delay.

    Please check the sample.

    Them mux with a audio delay/advance to account for it.
