Seperating MPEG to MPEG-video and MPEG-audo

    Hi

    To create a VCD one must have seperate video and audio, and then combine
    them with something like TMPGEnc into the correct format.

    If I have an MPEG file which already has the correct size, aspect ratio,
    frame rate etc., is there a utility to seperate it into video and audio
    ready for TMPGEnc? If I use Edit Studio it takes 5 minutes per minute of
    video to generate the video-only file.

    Thanks,
    Nigel

  3. TMPGEnc does this - go to the first menu, then MPEG tools then simple demux
    gives you an M2V or M1V video file and a Mp2 audio file.

    What I cannot understand is since TMPGEnc makes files for VCD or SVCD or
    DVD why don't you just take the MPEG file you have and use the wizard to
    make VCD/SVCD/DVD ready files? If they are muxed MPEG 1 or MPEG 2 files it
    uses the audio from the muxed file without splitting it in the same program
    and putting the two files back. Just select a MPG file from the list and
    you wil see it put the video and audio in for you with the same file name
    in both areas.
    Seems like a lot of work to divide and then rejoin audio and video in the
    same file in the same program.

    I take it you haven't actually tried to use it yet.

    I have used TMPGEnc to combine the files which I produced with Edit
    Studio. I will try it to demux.

    I have an idea that the file structure for VCD differs enough that
    trying to do it in one step in TMPGEnc would end up in demux totally
    and then combine again afterwards. All you would save is the step of
    having to say "combine these two files".

    Thanks for the info,
    Nigel
