Switching Between the Canvas and Digital Cinema Desktop Preview Modes

If you want to switch between the Canvas and any of the Digital Cinema Desktop
Preview modes, you have a couple of options.

To switch between your last chosen Digital Cinema Desktop Preview mode and
the Canvas, do one of the following:

m

Choose View > Video Out > Toggle Last.

m

Click the Toggle Video Out button.

This button is located in the button bar of the Canvas.

Connecting Speakers When Using External Video Monitoring
Modes

If you are in any of the Digital Cinema Desktop Preview modes or the Canvas Playback
mode, your audio speakers should be connected to the built-in audio port on the
computer. If you are previewing video on an external DV device connected via FireWire,
your speakers should be connected to the DV device, such as your DV deck or
camcorder.

Note:

Since you’ll often be changing the location of the audio speakers according to

the external video monitoring mode you choose, it is a good idea to connect an audio
routing device, such as an audio mixer or a simple Y-split audio adapter, to both the
computer’s built-in audio port and the DV deck or camcorder’s audio output to the
audio speakers.

Troubleshooting Digital Cinema Desktop Preview

If you are experiencing trouble with any of the Digital Cinema Desktop Preview modes,
review the following:

Â

The screen saver must be turned off for the computer display being used for Digital
Cinema Desktop Preview.

Â

Full-motion video can be processed by AGP graphics cards only. For triple monitor
configurations, it is recommended that displays connected to PCI graphics cards be
used to display windows in which playback does not occur, such as the Browser.

Â

Due to the refresh rate of LCD computer displays, 1080i60 material may exhibit
temporal artifacts during playback.

Â

Video playback on an NTSC or PAL video monitor differs from playback on an LCD
computer display. LCD computer displays have a longer decay period between each
frame as compared to lines being scanned on a CRT. At times, the same video image
will be visible on screen for a period of up to four to seven frames.

Â

Interlaced material is scanned at the frame rate rather than the field rate, so when
viewing 1080i60, both fields are drawn simultaneously, which may result in visual
interlacing.
