    Hi. I plan to make a music video dvd of music I made, therefore audio quality is a first priority. When I author the dvd can I just use a straight up wav file? Will it compress my wav file into something of lesser quality? If so what format should I use for the best quality?

    I think most authoring programs should be able to use wav without compressing it.

    You need to select "lpcm" in the audio settings to use the highest, uncompressed setting.

    Of course you have to use lower video bitrates to make it fit.

    "Audio:48000 Hz, 32 - 1536 kbps
    Up to 8 audio tracks containing DD (Dolby Digital/AC3), DTS, PCM(uncompressed audio), MPEG-1 Layer2. One audio track must have DD or PCM Audio."

    That means one 16bit 48KHz stereo pair can be handled uncompressed from a camcorder or up to 8 channels if imported.

    8 channels full 16bit 48KHz PCM will stream around 6,144 KHz leaving only about 3500 Kb/s for video. Don't push it if you want it to work on all DVD players.

    Of course, most DVD players see only two PCM channels at a time depending on authoring.

    Thanks! It is only a stereo wav so how much bitrate does that leave for video?

  6. With 48KHz 16-bit/channel stereo LPCM audio (=1536Kb/s) on a DVD the maximum allowed video bitrate is 8000Kb/s as far as I know.

    The max combined bitrate is 10,080kbps, and with audio at 1536kbps, that leaves a touch over 8500kbps for video (and subtitles) in theory. Of course this does not take into effect the running time of your video; just the max permissable bitrate according to the DVD spec.
    If in doubt, Google it.
