  1. Hi, I have a 3D movie that was ripped using MakeMKV to a 3D MVC MKV file. I want to re-encode the file to just a standard 2D MKV... essentially just keeping the left eye information and discarding the right eye. I realize I can just take the left eye video from the original source disc... but I want to learn how to extract the left eye from a 3D MVC MKV.

    Here's the video info:

    ID                                       : 1
    Format                                   : AVC

    MultiView_Layout                         : Both Eyes laced in one block (left eye first)

    Forced                                   : No
    Any suggestions? Maybe using an avisynth script with x264? Thanks.

  2. If the left eye is the base view you could simply open it with a decoder that doesn't support the 2nd view. I.e. ffmpeg, x264cli with ffms or lavf input support or AviSynth ffms2.

  3. I initially tried x264CLI kMod but it wouldn't recognize the input file. But I ended up just using the x264 encoder in Avidemux... worked like a charm.
