Chapter 1 Getting to Know Motion 151
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 a cinema
display as an external monitor. The following external video monitoring choices are
available:
 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.
 Pros: The video always maintains proper aspect ratio and does not exhibit scaling
artifacts due to magnification.
 Cons: 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.
 Pros: This format gives you the biggest picture possible and maintains the proper
aspect ratio.
 Cons: 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.
 Pros: This format gives you the biggest picture possible and maintains the proper
aspect ratio.
 Cons: 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.
 Pros: More accurate assessments of video quality can be made.
 Cons: Not useful for general viewing. 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.
