The following sections guide you through configuring the MPEG-1 output file format for DVD use. This process creates two settings, one for video and another for audio, creating elementary streams.

Stage 1:Creating the MPEG-1 Video for DVD Setting

Create the setting for an MPEG-1 elementary video output file suitable for DVD. See

Creating the MPEG-1 Video for DVD Settingfor more information.

Stage 2:Creating the MPEG-1 Audio for DVD Setting

Create the setting for an MPEG-1 elementary audio output file suitable for DVD. See

Creating the MPEG-1 Audio for DVD Settingfor more information.

Stage 3:(Optional) Creating an “MPEG-1 for DVD” Group and Destination

Optionally, you can “package” your newly-made settings in a custom “MPEG-1 for DVD” group and destination. SeeOptional—Creating an MPEG-1 for DVD Group and Destination

for more information.

Creating the MPEG-1 Video for DVD Setting

The following sections create the setting for an MPEG-1 elementary video output file suitable for DVD.

• Stage 1: Creating the MPEG-1 Video for DVD Setting

• Stage 2: Configuring the Video Settings

• Stage 3: Making an Elementary Video Stream

Stage 1:Creating the MPEG-1 Video for DVD Setting

This section describes creating MPEG-1 video settings for DVD use. To open the Settings tab and create a new setting

1 Open the Settings tab, and choose MPEG-1 from the “Create a New Setting” (+) pop-up menu.

2 Name the new setting “MPEG-1 Video for DVD.”

SeeCreating a Setting from Scratchfor more information.

Stage 2:Configuring the Video Settings

This section describes configuring MPEG-1 video settings for DVD use.

To open the MPEG-1 Encoder pane and configure the Video settings for DVD

1 Click the Encoder tab and choose MPEG-1 from the File Format pop-up menu.

2 Click the Video button in the MPEG-1 Encoder pane to open the Video tab.

Select to enable the Video tab.

Choose the frame rate. The file extension changes to .m1v once the Audio tab is disabled.

Choose the bit rate. Select DVD to set the resolution to match the frame rate.

3 Select the Enabled checkbox.

4 Choose the frame rate that matches your source video, either 29.97 or 25, from the Frame Rate pop-up menu.

5 Select the DVD button.

This sets the resolution of the output to match the selected frame rate.

6 Choose the bit rate to use with the Bit Rate slider, or enter a value directly.

The typical value used for DVD projects is 1.15 Mbps, with 1.856 Mbps being the maximum allowed.

Stage 3:Making an Elementary Video Stream

In order for the output media file to be an elementary video stream, you must turn off the audio setting.

To turn off the audio for the video setting

1 Click the Audio button in the MPEG-1 Encoder pane to open the Audio tab.

This ensures that this setting (preset) will only create an elementary video stream and sets the file extension to .m1v.

Deselect to disable the Audio tab.

3 Click the Save button (in the lower-right corner of the Inspector) to save this setting. This saves the “MPEG-1 Video for DVD” setting.

Creating the MPEG-1 Audio for DVD Setting

The following sections create the setting for an MPEG-1 elementary audio output file suitable for DVD.

• Stage 1: Creating the MPEG-1 Audio for DVD Setting

• Stage 2: Making an Elementary Audio Stream

• Stage 3: Configuring the Audio Settings

Stage 1:Creating the MPEG-1 Audio for DVD Setting

This section describes creating MPEG-1 audio settings for DVD use. To open the Settings tab and create a new setting

1 Open the Settings tab and click the Add (+) button. This adds a new setting to the existing list.

2 Name the new setting “MPEG-1 Audio for DVD.”

SeeCreating a Setting from Scratchfor more information.

Stage 2:Making an Elementary Audio Stream

In order for the output media file to be an elementary audio stream, you must turn off the video setting.

To turn off the video setting

2 Click the Video button in the MPEG-1 Encoder pane to open the Video tab.

Deselect to disable the Video tab. The file extension changes to .m1a once the Video tab is disabled.

3 Deselect the Enabled checkbox.

This ensures that this preset will only create an elementary audio stream and sets the file extension to .m1a.

Stage 3:Configuring the Audio Settings

Use the following settings to create an MPEG-1 audio file for DVD. To open the Audio tab and configure the Audio settings for DVD

1 Click the Audio button in the MPEG-1 Encoder pane to open the Audio tab.

2 Select the Enabled checkbox.

Choose the 48 kHz sample rate. Choose the bit rate. Select to enable

the Audio tab.

Select either Stereo or Mono.

3 Choose 48 kHz from the Sample Rate pop-up menu.

4 Select Stereo when using two-channel audio sources or Mono when using one-channel audio sources.

The typical values used for DVD projects are 192 kbps and 224 kbps.

6 Click the Save button (in the lower-right corner of the Inspector) to save this setting. This saves the “MPEG-1 Audio for DVD” preset.
