System information
5. Select the Recompress edited frames check box if you want to recompress edited frames in your
project before previewing. When the check box is cleared, edited frames will not be passed to your
preview device.
If you're previewing a project that consists of DV media with no compositing or transitions, the DV
will be passed directly to your preview device. If, however you'd added a 6-frame crossfade, the
crossfade would be passed to the preview device only if the check box is selected.
6. Select the Display frames in Video Preview window during playback check box if you want to
preview on the external monitor and in the Vegas Pro Video Preview window simultaneously.
When the check box is cleared, video is sent only to the external monitor.
7. Select the Use project output rotation setting check box if you're rendering a rotated project and
want to use the Output rotation setting from the Project Properties dialog for previewing your
project.
When the check box is cleared, the media is rotated according to its Media Properties setting, but
the Video Preview output is unrotated—you can use this setting to proof your project on an
unrotated display.
For more information, see "Creating Rotated Projects" on page 65.
8. Choose a setting from the Stereoscopic 3D mode drop-down list if you're working with a
stereoscopic 3D project and want to override the project settings for previewing your stereoscopic
3D project on an external monitor.
For more information, see "Stereoscopic 3D editing" on page 201 and "Setting up stereoscopic 3D
previews" on page 205.

connected.
You can click the Identify Displays button to determine which display corresponds to each setting in
