    BD Ripper (3D Plus) Block artifacts when converting Blu-Ray to MKV

    Hello,
    I'm new to converting my Blu Rays to files I can play on my computer.
    1) I'm not certain if I should use AVI or MKV as the output format, it seems most people use MKV for Blu-ray so I conform to that, can anyone tell me if this is the preffered format for Blu Ray? If so why?

    2) The rendering quality is very good, however, every now and then the are lots of blocky artifacts (see as example the attached snapshots taken from VLC). This is usually preceded by a short pause in playback. after 2-3 seconds the playback resumes without those artifacts. Is there anything I should be looking out for in the program settings?
    These artifacts seem to happen much more frequently in the 1st few minutes of the movie.

    Running Windows 7 64 bit.
    VLC 1.1.5

    In DVDFab 8.0.6.6 I use the following settings for Blu-Ray Ripping:
    ----------------------
    Device: MKV
    Output Type: Video+Audio
    Encoding Method: High Quality Encoding (2 pass)
    Fixed File Size: 4000 MB
    Frame Resolution: 1920x1080
    Split: No Split
    Frame Rate: Same as source
    Audio Format Bitrate: Same as source
    Audio Format Channel: Same as source
    Volume: 100%
    -----------------------

    3) Note: Playing with WMP 12 after installing Direct-X update and CCCP Codec pack from http://www.matroska.org/downloads/windows.html doesn't seem to have this sort of problem, could it be a problem with VLC? However, I don't seem to manage to switch off the subtitles during playback in WMP

    Thank you,
    Guy.

    This probably indicates that the bitrate is spiking too high for your playback. In VLC go to Tool > Media Information > Statistics (Tab) and watch the Stream Bitrate.

    Is the file located on the local hard drive, an external usb drive, or a network drive during playback?

    Also, if this is a full length movie then 4000MB at 1080p resolution seems a bit harsh of a conversion but to each their own.

      File is on local hard drive.
      highest bit rate is around 6500 kb/s but funnely enough, at the scenes where is messes up, it's not that high.
      Do you mean 4000MB seems too small? The video quality seems fine but could a larger file size help?

      Thanks,
      Guy.

        Larger file size is not likely to help. If the video quality is fine for you then keep with it. Sorry, I have no further guesses as to what is in the file that VLC is choking on.

          Hi, fisherg,

          You may give these some consideration:

          1. Open Common Settings->General->A/V Codec, set video decoder and encoder as software, then convert again to see the result;

          2. Copy this movie to your HDD first and then play the copied folder on your computer to check if it can play smoothly. If can, you can then load the movie folder to do the conversion to see the result;

          3. Use other players, eg, PowerDVD to play the MKV file to see the result.

          Regards
