Apple Final Cut Pro 7 - Manual (Page 240)

• Con: This mode is not useful for general viewing. No scaling or pixel aspect ratio
adjustments are made, even when the video is larger than the display.
Using Digital Cinema Desktop Preview to Monitor Your Video
Unlike using a third-party video interface (or DV via FireWire), directly monitoring video
on a computer display does not introduce video latency (inherent processing delays).
Therefore, Final Cut Pro ignores the frame delay offset setting when you preview your
video on a computer display connected to a graphics card.
Tip: Regular editing commands still work when full-screen video is presented on the
main display. This means you can still set In and Out points, use the J, K, and L keys for
playback, and so on. For a list of shortcut keys, choose Tools > Keyboard Layout >
Customize.
To turn on Digital Cinema Desktop Preview
1 Choose View > Video Playback, then choose one of the available Digital Cinema Desktop
Preview options.
2 Choose View > External Video > All Frames (or press Command-F12).
3 To listen to audio in sync with video output on a computer display, make sure the audio
frame offset value is set to 0.
For information about how to set the frame offset for audio/video latency compensation,
see
“Compensating for Video Latency by Specifying a Frame Offset.”
Important: Command-F12 is the default keyboard shortcut for turning external video
monitoring on and off. When full-screen video is presented on the main display, the menu
bar cannot be seen, so you need to use this keyboard shortcut.
It’s important to know how to turn off the Digital Cinema Desktop Preview option,
especially when you are using full-screen mode on the main display.
To turn off Digital Cinema Desktop Preview
Do one of the following:
µ
Press Command-F12.
µ
Press the Escape key.
Troubleshooting Digital Cinema Desktop Preview

following:

the “Start screen saver” slider to Never).
