MPEG-1 Transcoding Workflow

This section gives step-by-step instructions for setting your MPEG-1 attributes prior to creating MPEG-1 output files with Compressor. Make your MPEG-1 settings from the MPEG1 Encoder pane by either modifying an existing setting or creating a new setting. See the following steps for working with the MPEG-1 output file format.

Example MPEG-1 Settings

The settings you use depend on whether you are encoding for use on the web or in a DVD project.

Encoding for the Web

Use the following settings when encoding MPEG-1 system streams for the web.

Video tab:

  • Frame rate: Automatic
  • Purpose: Web
  • Bit rate: As low as you can set it and get acceptable picture quality

Audio tab:

  • Sample rate: 44.1 kHz
  • Channels: Stereo with two-channel sources; Mono with one-channel sources
  • Bit rate: As low as you can set it and get acceptable audio quality; use higher bit rates when encoding stereo audio

Encoding for DVD

Use the following settings to configure two settings when encoding MPEG-1 elementary streams for DVD authoring.

Video elementary stream setting (Video tab):

  • Frame rate: 29.97 for NTSC or 25 for PAL
  • Purpose: DVD
  • Bit rate: 1.15 Mbps

Video elementary stream setting (Audio tab):

  • Enabled checkbox: Deselected

Audio elementary stream setting (Video tab):

  • Enabled checkbox: Deselected

Audio elementary stream setting (Audio tab):

  • Sample rate: 48 kHz
  • Channels: Stereo with two-channel sources; Mono with one-channel sources
