    Hi, I usually can convert .mkv files myself, but these files have something I haven't actually encountered before. Here is what shows up when I run MKVExtractGUI to check what's inside the mkv:

    the video track is :V_MPEG4/ISO/AVC
    the audio track is: A_AAC

    the audio, I'm pretty sure I can just extract with MKVExtract and convert to mp3 later, but the video, I can't use VirtualDubMod to direct stream copy like I usually do. So does anyone know any methods to do this, any help would be appreciated.

    Just some technical stuff:

    The video stream is an AVC stream - an h264 HD stream. If you want to convert it with VDubMod, you'll have to install Avisynth and create an Avisynth script and open the script in VDM.

    Otherwise, you can go with the two options above. I don't know if they'll accept that video stream, though, since it's a relatively new standard. That, and I'm also not sure of the quality those two produce - whether they're simply one-click solutions, or if they allow for precise encoder tweaks, etc. But if it works for you, then I'm all for it.

    Good luck.

    KajNrig, I do have AviSynth installed, could you tell me what I would need to type in order to make the correct Avisynth script so I can open it in Virtual Dub? Thanks in advance.

    It's pretty simple. If you just want VDubMod to load the video, open up Notepad and type:

    DirectShowSource("C:/...file path.../file.mkv")

    ...and save as an Avisynth script - ".avs".

    Then you load it up in VDubMod (hopefully there won't be any issues), do the whole converting thing, and you should have yourself an .avi file. But just the video.

    But I believe you can mux in the audio, as well. You know how to do that, right?

    do I leave the quotes and parentheses, if I do, then Virtual Dub crashes if I try to open up the .avs file.

    Well, you're SUPPOSED to keep those there... I dunno why it crashes, then... maybe there's a plugin it's missing or something. I know that if you want to work with the raw h264 stream, you have to frameserve it and all this junk first to get Avisynth working with it...

    I dunno. You could try MeGUI to re-encode instead. It's always worked for me. Plus it's more geared towards those kinds of files (h264) anyway, so it's bound to be more compatible.

    generally, the common video converter can do it. MKV is a container format and it has the independent video codec and audio codec. It is the same as AVI in this aspect.
