The Digital Cinema Desktop feature in Final Cut Pro HD allows you to use your computer's display for full-screen playback monitoring. Under some circumstances, you may see only a green screen instead of your sequence's video. This can happen if you are using 10-bit uncompressed settings in your Final Cut Pro sequence.
To workaround this issue, you can monitor playback in the Canvas window on your computer display, or monitor playback on an external NTSC or PAL monitor. This issue will not affect the final output to file or tape.
