Apple Final Cut Pro 7 - Manual (Page 237)

If no video device is connected when Final Cut Pro opens, but you connect one while
Final Cut Pro is open, you will not be able to use it immediately. If the video device
does not appear in the Video Playback submenu of the View menu, make sure the
device is connected and turned on, then choose View > Refresh A/V Devices.
• Do not show warning when audio outputs are greater than audio device channels: This
option affects the Audio Outputs tab of the Sequence Settings window. If this option
is not selected, you will see a warning every time you choose more audio outputs than
are available from the currently selected audio device.
For example, if your audio device has only two audio outputs, and you configure your
sequence to have six audio outputs, a warning dialog appears when you click OK to
close the Sequence Settings window. To prevent this warning from appearing, select
this option.
Controlling When External Video Output Is Updated
Updating the external video output requires processing power. You can control how
often the external video output is updated.
To set the external display option
1 Choose View > External Video.
2 Choose an option from the submenu:
• Off: Turns off external video and audio output so nothing plays on your video monitor.
This allows you to play more real-time effects.
• All Frames: Updates every frame to the external video output. This includes scrubbing,
jogging, and playback.
• Single Frames: Updates external video output when you manually choose to display a
frame. This frees your computer’s processor to calculate more real-time effects but still
allows you to preview single frames on your external video output device. When this
option is selected, you can update the video output device by choosing View > External
Video > Show Current.
