Viewing on an External Monitor
When using the Mac OS X version of Shake, you can preview your work on a second
display. This can either be a second computer monitor, or a broadcast video monitor
connected to a compatible video output card (compatible video output cards support
an extended desktop). For more information on compatible video cards, go to
http://
www.apple.com/shake/.
Note: The broadcast viewer option is not available on the Linux version of Shake.
To enable viewing via an external monitor:
1 Click the Globals tab.
By default, the format parameter is set to Custom.
2 Choose the format of your footage from the format pop-up menu. For example, if you
are working with NTSC D1 (4:3) non-drop frame footage, choose NTSC ND (D1 4:3) from
the format pop-up menu.
3 In the Viewer shelf, click the Broadcast Monitor button.
The external video monitor mirrors the image displayed in the Viewer, which means
that you can output the image from any selected node (the node displayed in the
Viewer), as well as the Viewer scripts, VLUTs, and so on. In the Node View, the Viewers
displaying the node are printed under the node (for example, 1A, 2A).
Note: If a broadcast Viewer is spawned prior to setting the correct format, the image
may appear incorrect if the wrong aspect ratio is assigned. Go to the Globals tab and
select the correct ratio from the format pop-up menu.
Customizing External Monitor Output
A group of parameters in the monitorControls subtree of the Globals tab let you adjust
how the image sent to an external monitor will be displayed.
broadcastViewerAspectRatio
By default, this parameter is a link to
script.defaultViewerAspectRatio , which
mirrors the setting in the format subtree of the Globals tab. When first launched, Shake
looks at the system’s monitor card and outputs the proper aspect ratio based on the
format you select in the Globals tab. For example, if you have a D1 card and you select
NTSC D1 from the format parameter, Shake displays nonsquare pixels in the Viewer and
sends square pixels to the video monitor.
Note: If you change the value of the broadcastViewerAspectRatio using the slider or
the value field, the link to defaultViewerAspectRatio is removed. As with all Shake
parameters, you can enter another expression in the broadcastViewerAspectRatio
parameter to reset it.
