Apple Soundtrack Pro 3 - Manual (Page 359)

Some broadcast-quality video output devices receive both the video and audio from a
project. When you use a video output device that supports both video and audio output,
Soundtrack Pro automatically routes your audio output to this device to provide the best
possible synchronization of the audio and video.
You can also play a project’s video externally using Digital Cinema Desktop. Using Digital
Cinema Desktop, you can connect an Apple Cinema Display to your computer and play
the video full-screen through the Cinema Display while using another monitor for editing.
To play the video through a video output device, you must configure Soundtrack Pro to
use the device in Soundtrack Pro Video Out Preferences.
To configure Soundtrack Pro for a video output device
1 Choose Soundtrack Pro > Preferences, then click the Video Out button.
2 In the Video Out pane, choose the device you want to use from the Video Output Device
pop-up menu.
The menu lists only devices that are connected to your computer.
3 Optionally, select the Use Quarter-size Frames checkbox to reduce the frames sent to the
video output device. Sending quarter-size frames can result in better performance,
especially for devices using FireWire DV output.
4 Click the close button at the upper-left corner of the Preferences window to close the
window.
You can switch the output to the video output device on or off when the project is not
playing. The video appears in the Video tab whether output to the video output device
is switched on or off.
To switch off output to an external video output device

To switch on output to an external video output device
µ
Choose View > Show > Show External Video.
If you have added the Video Out button to the Toolbar, you can also click the button to

A video output device can only be controlled by one application at a time. If you hide
Soundtrack Pro or bring another application to the foreground while playing video through
a video output device, Soundtrack Pro maintains control of the output device and
continues playing. If you hide Soundtrack Pro or bring another application to the
foreground when video is not playing through a video output device, Soundtrack Pro
releases control of the output device.
