Apple Final Cut Pro 7 - Manual (Page 848)

• FireWire DV: If you connect a DV camcorder or deck to your computer, this option
becomes the default setting.
• Other available audio interfaces: If you have a third-party video or audio interface
installed, it appears in this list.
Depending on your hardware, additional options may be available to configure your
audio interface.
3 Click Options, then make choices for the following:
• Channels: Choose the number of channels your audio interface can output. You can
assign sequence tracks to these channels by creating an audio output preset. For more
information, see
“Creating and Saving Audio Output Presets.”
• Bit Depth: Choose a supported bit depth for the audio. Sixteen-bit audio is compatible
with most DV equipment. For high-resolution output and export, 24-bit audio is
preferred.
• Sample Rate (Hz): Choose a standard sample rate from the pop-up menu. For professional
video applications, 48 kHz is typical, though 96 kHz is becoming more popular.
4 Select or deselect the following alert message options:
• Do not show External A/V Device Warning when device not found on launch: Select this
checkbox to turn off the alert message when selected devices cannot be found during
application startup.
• Do not show warning when audio outputs are greater than audio device channels: When
selected, this option disables the following message: “The selected external audio
device does not support N outputs. Unsupported outputs will be ignored during
playback on this machine.” This message appears when you assign more audio output
channels to a sequence than the audio interface currently selected in the Audio/Video
Settings window can support. For more information about setting audio outputs, see
“Assigning More Audio Outputs Than Your Hardware Supports.”
Final Cut Pro supports “audio follows video” output switching, which means that changing
the selected video interface automatically switches the audio to the same interface (when
possible).
To turn on “audio follows video” switching for video and audio outputs
1 Choose View > Video Playback, then select a video output from the submenu.
