Setting Up Your Editing System
Digital Cinema Desktop Preview - Raw
This mode shows your video data with as little processing as possible—there is no
scaling or pixel aspect ratio correction. For example, a 720p frame (1280 x 720) shown
in raw mode on an 800 x 600 display only shows 800 x 600 pixels of the image. This can
be useful for engineering evaluations of the image.
 Pro: More accurate assessments of video quality can be made
.
 Con: 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 an AGP 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, or see the Final Cut Pro 5 Quick Reference.
To turn on Digital Cinema Desktop:
1
Choose View > Video Playback, then choose one of the available Digital Cinema
Desktop Preview choices.
2
Choose View > External Video > All Frames (or press Command-F12).

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:
m
Press Command-F12.
m
Press the Escape key.
