  • DVDA recompreses audio in BR even with Vegas template

    Posted by John Lenihan on May 13, 2011 at 5:09 pm

    I am trying to render with with a conforming Template in Vegas 10d to burn a blu ray disk after dvd architect.

    The source is 1920 x 1080 60i.

    I chose one of the templates suggested by the Vegas help system. That is

    1920 x 1080i and audio of ac3 at 192 kbits.

    It created an m2ts file.

    Loaded that into DVD architect 5.2 and it was happy. But when I went to create the blu ray iso file, it says that it must recrompress the audio.

    I tried every setting of ac3 on architect settings beside the 192 kbit. It keeps wanting to recompress.

    What am I missing.

    Are you saying that you selected one template that had both video and audio? If that’s the case, then that’s your problem. You must render the AC3 as a separate file.

    John,

    I know that is the case for mpeg files in the past.

    But this is right out of the help section in Vegas
    search for Bluray

    Then read the avc compliant. Quote:

    If you’re using Vegas Pro software, you can use the AVCHD rendering templates to render a compliant video file including 5.1 surround AC-3 audio.

    Yes, so perhaps when it says that it’s processing the AC3 audio it’s just stripping it out into an elementary stream and not really re-encoding it? I must admit, it’s a bit of a mystery sometimes as to what keeps DVD Architect happy when encoding files.

    John,
    Thanks for at least proving that I am not missing anything here.

    It seems that Sony isn’t investing very much in the DVD architect tool. In fact, it seems like the programmers on the Vegas Side are trying to leapfrog the DVD architect programmers.
