DVD Compliant Audio Help Requested

Discussion in 'Amateur Video Production' started by Richard Forester, Nov 28, 2003.

  1. I am going to be taking some VHS tapes and converting them to DVD. I also
    have some MPEG-2 recordings from my All In Wonder. My question is, does
    anyone know if I must have 256kbps audio to be DVD compliant? Or is 224kbps
    acceptable?

    Thank you for your help!

    According to http://dvddemystified.com/dvdfaq.html#3.6 ...

    MPEG audio is multi-channel digital audio, using lossy compression
    from original PCM format with sample rate of 48 kHz at 16 or 20
    bits. Both MPEG-1 and MPEG-2 formats are supported. The variable bit
    rate is 32 kbps to 912 kbps, with 384 being the normal average rate.
    MPEG-1 is limited to 384 kbps.
    ...
    MPEG audio is not used much on DVDs, although some inexpensive DVD
    recording software programs use MPEG audio, even on NTSC discs,
    which goes against the DVD standard and is not supported by all NTSC
    players.

    In spite of that last part, I've never heard anyone say that their
    player won't play an NTSC disc because it only had MP2 audio on it,
    and I make most of mine that way (at 384kbps). You should be OK with
    224kbps although I've had some sync trouble with Ulead DVD Movie
    Factory 2 when trying to use rates other than 384kbps (other authoring
    software I've used doesn't have that problem).
