• Show Advanced Settings: This checkbox remains dimmed unless the codec you selected
from the Format pop-up menu offers options. It is recommended that you contact the
manufacturers of these codecs directly for more information about the additional
options they offer.
QuickTime Audio Sample Sizes and Rates
If you have the disk space and bandwidth, it is best to leave your audio uncompressed.
Uncompressed audio normally uses 8-bit (phone quality) or 16-bit (CD quality) samples.
Compressor supports up to 64 bits per sample floating point and a maximum sample
rate of 192 kHz.
Choosing an Audio Codec
AAC is a good general-purpose audio delivery codec and it is compatible with a wide
variety of playback devices. For QuickTime movies playing on slower computers, IMA 4:1
is a better choice because it is less computer intensive, thus allowing the computer to
focus on the more challenging video stream. See QuickTime Audio Codecs for more
information about audio codecs.
QuickTime Transcoding Workflow
The following sections outline the transcoding process required to create QuickTime
output media files.
• Stage 1: Opening the QuickTime Encoder Pane
• Stage 2: Adding a QuickTime Video Codec
• Stage 3: Adding a QuickTime Audio Codec
Stage 1: Opening the QuickTime Encoder Pane
There are many QuickTime video and audio codecs that you can choose from in
Compressor. You access all codecs via the Compression Settings and Sound Settings
dialogs, opened from the QuickTime Encoder pane by clicking the Video Settings and
Audio Settings buttons.
To confirm or create a QuickTime Movie 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 QuickTime Movie from the “Create a new setting”
(+) pop-up menu.
2 Open the Encoder pane in the Inspector window.
