    MPEG audio for DVDs is MPEG Layer II encoding, not Layer III (aka MP3).

    Can you compress to MPEG Layer II in Wavelab?

    Also, please provide the audio encoding settings.

      Yes, sorry for confusing that issue.

      Yes I can, and when the settings are 48kHz and 192 kbps, the artifacts are there in Wavelab encoded file as well. So its the same error in the encoder for Wavelab as in ProCoderExpress.

      The story seems to be to keep well away from MPEG2 audio output for the DVD. Its going to be only 48/16 PCM WAV for me.

      Thanks for your help Brandon.

        You're welcome David.

        MPEG-1 Layer II audio compression is... well... just okay.
        It was the thing when it first came out back in the early 90's though. I remember running DOS compressors on them.

        MPEG-1 Layer III, on the other hand, is much better.

        Still, for DVD use, my preference would be AC-3. EDIUS v4.5 will include AC-3 encoding, both in the new DVD authoring as well as timeline export, so once the upgrade comes out you can move toward using AC-3 instead.

          Hi David / Brandon,

          I always stick to WAV for my DVD productions. Especially when I record in concert halls (classical recordings). The sounds are so much better than any encoded sounds (MPEG Layer 2, Layer 3, or even AC-3). Really telling in the depth of the recorded sound.

          I use a 24 bits 96Khz digital sound recorder for the original sound recording, which I then merge into the video (after downsampling to 16 bits, 48Khz).

          With a DVD - no problem with space.
