Choosing an Audio Codec for Distribution
MPEG-4 Audio (AAC) is a good general-purpose audio delivery codec and is compatible
with a wide variety of playback devices. For slower computers, less-compressed formats,
such as IMA, or completely uncompressed formats, such as AIFF, may be better choices,
because they are less processor intensive, thus allowing the computer to focus on the
more challenging video stream.
Configuring AIFF Settings
When you choose the AIFF output file format as your output format, you can only create
audio settings (because it is an audio-only format). If you want to add an audio codec to
your AIFF preset, you need to open the Sound Settings dialog and choose your audio
codec settings from there.
To create an AIFF audio codec setting
1 In the Settings tab, do one of the following:
• Make sure that the correct setting is selected.
• Create a new setting by choosing AIFF from the “Create a new setting” (+) pop-up
menu.
2 Click the Settings button in the AIFF Encoder pane.
The Sound Settings dialog opens.
Choose an audio codec
from the Format
pop-up menu.
3 Choose an audio codec from the Format pop-up menu and either accept its defaults or
customize the other audio codec settings (Format, Channels, Rate, and Options, if
available). See About the Sound Settings Dialog for more details.
Note: You can see full details of the current contents of your preset by viewing the
QuickTime AIFF Summary table in the Encoder pane.
4 Click OK to save your settings and close this dialog.
