Audio Podcasting Workflow

Compressor makes it easy to create an enhanced audio podcast based on the MPEG-4 output format. An enhanced audio podcast includes podcasting information such as chapter and podcast markers with artwork and URLs, as well as a variety of text annotations. Follow the instructions below to create an audio podcast.

Stage 1: Configuring the MPEG-4 Output for Audio-Only Output

Follow the steps below to configure MPEG-4 settings for audio-only output (such as podcasts).

To open the MPEG-4 Encoder pane and configure it for audio-only output media files
  1. In the Inspector window, click the Encoder pane and choose MPEG-4 from the File Format pop-up menu.

  2. Click the Video button to open the Video pane.

  3. Deselect the Video Enabled checkbox.

  4. Click the Audio button to open the Audio pane.

  5. Select the Audio Enabled checkbox.

    This configures the MPEG-4 output to be an audio-only (.m4a) file. You can also configure the other settings in the Audio pane as needed.

Stage 2: Including Podcasting Information

Follow the steps below to include podcasting information.

To configure the MPEG-4 output to include podcasting information
  1. Select the “Allow Podcasting information” checkbox at the bottom of the Inspector window.

    Figure. Video tab with the Video Enabled checkbox deselected and the "Allow Podcasting information" checkbox selected.

    This checkbox is available only when you have deselected Video Enabled in the Video pane. Selecting this checkbox ensures that any annotations you add, as well as any chapter and podcast markers with their artwork and URLs, are embedded with the output media file.

  2. Save the setting so that you can apply it to a source media file’s target.

Stage 3: Applying the Setting to a Source Media File’s Target

You must apply the setting to a source media file’s target to be able to configure the podcasting information that this setting allows you to add to the output media file. See Assigning Settings to Source Media Files for more information.

Stage 4: Entering Annotations for the Output Media File

You have the option of adding annotations (such as producer credits, keywords, and copyright information).

To open the Additional Information tab and enter annotations
  1. Click a non-target area of the job created by the source media file.

    The Inspector window shows the A/V Attributes, Additional Information, and Job Action tabs.

  2. Click the Additional Information tab.

  3. The Additional Information tab is where you can add annotations, such as a title and artist, to the output media file.

    Figure. Additional Information tab.
  4. Choose an item from the Add Annotation pop-up menu to add it to the output media file.

    The item appears in the Annotation column.

  5. Double-click the item’s Value column to type in the text annotation.

  6. Repeat this for each annotation item you want to add to the output media file.

While you have the job selected, you can optionally use the Job Action tab to have the output media file automatically added to a playlist in the iTunes library. For more information, see Adding Actions and About Job Actions.

Stage 5: Creating and Configuring Markers for the Output Media File

You can use the Preview window to add and configure chapter and podcast markers for the output media file. You can manually add the markers or import a chapter marker list. Each chapter and podcast marker can be named, have a URL added to it, and have a still image added as its artwork.

When played, the artwork displays along with the URL (which the viewer can click to open a web browser to show).

See Adding Markers to a Clip for details on adding and configuring markers in the Preview window.

Stage 6: Submitting the Job and Verifying the Output Media File

Once you have added the annotations and markers to the job, you can submit it to create the output media file.

After the encoding process finishes, you can open the output media file in QuickTime Player to verify that the markers, URLs, and artwork appear as intended.
