    Is there any utility to de-mux DivX or Xvid video, manipulate the audio properties, and mux it back without loss in video quality?

    One of my video clip had a very low audio output volume, need to increase it at least 300-400% louder (+ 9-12 db).

    In the past, I simply demux the video and audio using VirtualDub, and Goldwave to increase volume.

    If install proper audio codec and it will save Mp3/AC3/DTS/OGG to PCM wave, then I could easily convert it to MPEG-1 or MPEG-2 VCD/SVCD using TMPGEnc.

    But now I bought a Shinco 8830 DVD player which support DivX/Xvid, I no longer have to compromise with any loss of video quality after the VCD conversion.

    Any recommendation for a good Mux tool?

    what format is the audio in ?

    https://www.videohelp.com/tools?tool=AVI2WAV - demux

    Virtualdubmod will do the same


    Mp3gain or Wavgain will increase the volume. So will Audacity and a ton of other apps.

    this will remux the file https://www.videohelp.com/tools?tool=AVIMux_GUI
