Activity Forums Adobe Encore DVD Transcode Question

  • Transcode Question

    Posted by Devon Allistone on April 6, 2005 at 9:36 pm

    Hello,

    I recently have switched over from using Impression DVD-Pro, (a Pinnacle product) to Encore. The Capture Card I am using to digitize the video is a DC2000, (another Pinnacle product) which captures DVD complient MP2 files. My question is, why is it that Encore thinks my captured Video/Audio files are not DVD complient and need transcoding?

    Any help would be greatly appreciated.

    Thanks in advance…

    Devon

    Devon,

    Could you check an MPEG-2 file made with the DC2000 with Bitrate Viewer and post the following info (found in the lower right):

    Stream type:
    Resolution:
    Aspect ratio:
    Framerate:
    Nom. bitrate:
    VBV buffer size:
    Chroma format:
    DCT precision:

    Devon,

    All the parameters you posted are DVD compliant. I half expected the DC2000 MPEG-2 to be 704×480 instead of 720×480 which would force Encore to re-encode. But I don’t see anything Encore could object to.

    Are the DC2000 files multiplexed (audio and video) or are they elementary (video only) streams? If they are multiplexed, the audio is probably MPEG-1 Layer II and Encore’s transcoding may be only for the audio part, not the video.

    Hey RK,

    The DC2000 captures the files seperately. The audio file is captured as a .wav file.

    Rate: 48000Hz
    Format: 16 Bit stereo
    Uncompressed
    Interleave: 1/2 Second

    If the audio needs transcoding, I don’t really mind. Audio only takes a moment, but waiting for video transcoding takes a very long time. (8 minutes for a 3 minute clip)

    If you have any other ideas i’d love to hear them. I’m currently stumped.
