Troubleshooting Digital Cinema Desktop Preview
If you experience trouble when using Digital Cinema Desktop Preview, review the following:
 In Mac OS X System Preferences, the screen saver should be turned off (set the
“Start screen saver” slider to Never in the Screen Saver pane of the Desktop &
Screen Saver pane).
 Digital Cinema Desktop Preview works with AGP, PCI Express, and Intel Integrated
graphics cards.
 Because of the refresh rate of LCD computer displays, 1080i60 and 720p30 material
may exhibit temporal artifacts during playback.
 Interlaced media is scanned progressively at the frame rate instead of the field rate.
Therefore, when viewing formats such as 1080i60 or standard definition NTSC or PAL,
both fields are scanned simultaneously, which may result in interlacing artifacts.
 If you need to change your display resolution, do so prior to opening Final Cut Express.
 LCD Cinema Displays have a longer decay period between each frame when
compared to lines being scanned on a CRT. At times, the same video image may be
visible onscreen for a period of up to four to seven frames.
 Turning on Digital Cinema Desktop Preview playback can reduce the number of
real-time effects available in your sequence. However, the real-time status of these
effects is not updated in the Effects menu or the Effects tab of the Browser.
 Refrain from pressing the mouse button upon initially enabling Digital Cinema
Desktop Preview (especially in Single Display mode).
 Exposé is not supported with Digital Cinema Desktop Preview.
 Graphics files with a resolution of 1920 x 1200 and larger may not be displayed
properly.
 Digital Cinema Desktop Preview must be turned off when performing a Print to
Video operation.
 If you do not have a second display connected to your computer, only the Digital Cinema
Desktop Preview – Main option is available.
