    I have a MKV file (1.07 GB). I want to convert it to avi with this guide:
    http://forum.videohelp.com/topic239995.html
    After I extract I got in the folder a H264 file and AC3 file.
    How do i convert H264 to avi?
    will the result (the avi file I'll get) be the same quality as the original MKV file?

    It does'nt keep the quality. the original mkv file is 1.07 GB and the avi file I get is 332 MB. I used alltoavi.

    ***but the original file is mkv. after i extract it i get h264 file and ac3 file so the avi file i'll get be without sound?***

  10. As was pointed out, avc2avi is a command line application:

    http://forum.doom9.org/showthread.php?t=118267
    http://sourceforge.net/projects/avc2avi

    If your goal is to make an AVI file that will play on a Divx certified DVD player this will not work.

  12. You'll probably find the other tool Midzuki recommended, Avi-Mux GUI, easier to use.

    i tried Avi-Mux GUI, but it gives me mkv file back...

  14. The easiest way I know of to convert MKV to AVI is to use AviDemux. It has a GUI and can remux h.264 and ac3 audio from an MKV into an AVI. No quality will be lost.

    I downloaded Avidemux but how do I convert mkv to avi withe avidemux?
    Quote Quote  
  17. Open, select MKV file
    verify: video=copy, audio=copy, output=AVI (these are all the defaults)
    Save.

    This may or may not work.

    A more robust solution is to use MkvExtractGui to demux to .h264 and .ac3 files. Then use Avc2Avi to mux the .h264 file to an AVI, then use VirtualDubMod to mux the audio into the AVI.

  20. Avc2Avi is a command line application. You start up a command line interpreter (CLI) (Start -> All Programs -> Accessories -> Command Propmpt) and start typing in commands. Unfortunately, it's hard to explain how to use a CLI.

    To simplyfy things a bit, try this:

    1) Put AVC2AVI.EXE in your Windows System32 folder, usually, C:\Windows\System32.

    2) Put the attached MUX.BAT file in the same folder as your .h264 file.

    3) Drag your .h264 file onto the MUX.BAT file. Wait a few minutes. Press a key when prompted.

    That should create an AVI file in the same folder as the .h264 file -- with the same name, just .AVI added to the end. You should be able to play the file but it will have no audio. Add the AC3 audio with VirtualDubMod:

    0) Start VirtualDubMod.

    1) File -> Open Video File, pick AVI (you may get an error message about not finding an h264 codec, ignore it).

    2) Video -> Direct Stream Copy

    3) Streams -> Stream List...

    4) Press the Add button, select the AC3 file

    5) File -> Save As...

    MUX.BAT ??? what is it?
    Press a key when prompted---- ?
    Quote Quote  
  22. MUX.BAT is a batch file I created for you so you don't need to use the command promt and and type a bunch of commands by hand. Follow the intructions I gave.

    Oh, I see, attaching the MUX.BAT file directly didn't work. Here it is in a zip file:

    mux.zip

    With which program did you try to open your newborn .avi?
    BTW, had you already managed to play the MKVed h264 video
    on your computer? You need an AVC codec if you want to playback h264 ---
    ffdshow is a good start.

  28. Is the AVI file about the size as the mkv file? Does GSpot show the correct codec?

    what codec do i need? can you give me a direct link?
    the avi file is about the same size as the h264 file i convert
    Quote Quote  
  30. Judging by the file size it looks like the h.264 video was muxed into the AVI file.

    You should be able to play h.264 AVI with VLC or KMPlayer without a DirectShow codec (they have their own built-in decoders). Otherwise you can use ffdshow or CoreAVC to let any DirectShow based player to play h.264.
