Apple Motion 4 - Manual (Page 196)

Video Output: Set this pop-up menu to match the type of device connected to the
monitor. When this is set to anything other than None, Motion outputs a new frame to
the externally connected video monitor every time you release the mouse button (if the
Canvas has changed). If no deck or video monitor is connected, the menu is set to None.
If you have two computer displays, one can be used to view the Motion interface and
the Finder while the other can be used as a dedicated video monitor using an Apple
Cinema Display as an external monitor. The following external video monitoring choices
are available depending on the number and type of monitors connected:
• Digital Cinema Desktop Preview: The video is not scaled unless it is too large to fit on
the display. If the video signal is larger than the display, it is scaled to fit on the display.
The video always maintains proper aspect ratio and does not exhibit scaling artifacts
due to magnification, however, some formats, especially SD formats, may look very
small when displayed on large computer displays.
• Digital Cinema Desktop Preview - Full Screen: The video is scaled to fit the display in at
least one dimension. If the aspect ratio of the video signal and the computer display
do not match, the video on the display is letterboxed (black on top and bottom) or
pillarboxed (black on sides) as necessary.
This format gives you the biggest picture possible and maintains the proper aspect
ratio, however, scaling artifacts may be noticeable when viewed up close.
• Digital Cinema Desktop Preview - Main: Uses your main monitor as the Digital Cinema
Desktop display. The video is scaled to fit the display in at least one dimension.
This format gives you the biggest picture possible and maintains the proper aspect
ratio, however, scaling artifacts may be noticeable when viewed up close.
• Digital Cinema Desktop Preview - Raw: This mode shows the video data with as little
processing as possible. This can be useful for engineering evaluations of the image. No
scaling is done whatsoever.
Using this option, more accurate assessments of video quality can be made. This option
is not useful for general viewing, as no scaling or pixel aspect ratio adjustments are
made, even when the video is larger than the display.
Note: For example, a 720p frame (1280 x 720) showing in raw mode on an 800 x 600
display only shows 800 x 600 of the image.
• None: This mode is automatically selected when no deck or video monitor is connected
to your system.
Options: When the Video Output pop-up menu is set to one of the Digital Cinema Desktop
Preview settings, the Options button becomes active. For monitors connected via FireWire,
there is no need to adjust the options. For monitors connected via third-party hardware,
the options may have applicable settings.
