Specify advanced audio encoding settings

The audio encoding settings portion of the dialog box is automatically selected when an audio-only file is added to the encoding list. This portion of the dialog box is disabled when you encode video content without a combined audio track.

Note: Select an encoding profile from the Flash Video Encoding Profile pop-up menu, which sets a corresponding profile for the audio-only encoding format.
  1. To activate the advanced audio encoding options, select Audio. The default audio codec is mp3.
    Note: If the source video file has no audio track, or if you are encoding MPEG-1 files on a Macintosh computer, the audio encoding settings portion of the dialog box is disabled.
  2. Select a data rate from the Data Rate pop-up menu.

    The data rate is the bit rate of the mp3 audio stream. Better quality audio tracks, such as music and significant background noise, require a higher bit rate. Simple dialogue can be compressed to a much higher degree. Higher bit-rate settings (encoded at 80 Kbps or higher) are encoded in stereo, while lower bit-rate settings (encoded at 64 Kbps or lower) are encoded in mono.

  3. To move to the next panel of the Video Import wizard, click Next. To further modify the video clip, select another of the Advanced Settings tabs.
