• To set output options before viewing your document on the device, choose File > Export > Video Preview.
The Video Preview dialog box opens. If your document’s pixel aspect ratio doesn’t match the aspect ratio settings of
the display device, you will see an alert.
Note: The Send Video Preview To Device command uses the previous settings in the Video Preview dialog box.
3 Under Device Settings, specify options for the device that will display the image:
• (Mac OS) To specify an output mode, select NTSC or PAL. If the output mode and the device do not match (for
example, specifying NTSC for the output mode and connecting to a device in PAL mode), black patches appear on
previewing.
• To specify the aspect ratio of the display device, choose either Standard (4:3) or Widescreen (16:9) from the Aspect
Ratio menu.
Note: The Aspect Ratio setting determines which placement options are available.
4 Under Image Options, choose a placement option to determine how the image appears in the display device:
Center Places the center of the image at the center of the screen, cropping the portions that fall outside the display
edges of the video preview device.
Pillarbox Displays a 4:3 image on a 16:9 display with the center of the image at the center of the screen and gray bands
on the left and right sides of the image. This option is available only if you chose Widescreen (16:9) for the device aspect
ratio.
Crop to 4:3 Displays a 16:9 image on a 4:3 display with the center of the image at the center of the screen and without
distortion by cropping the left and right edges of the frame that fall outside the display edges of the video preview
device. This option is available only if you chose Standard (4:3) for the device aspect ratio.
Letterbox Scales a 16:9 image to fit on a 4:3 display. Gray bands appear on the top and bottom of the image due the
difference in aspect ratio between the 16:9 image and the 4:3 display. This maintains the display aspect ratio without
cropping or distorting the image. This option is available only if you chose Standard (4:3) for the device aspect ratio.
Crop To 14:9/Letterbox Displays a widescreen image cropped to a 14:9 aspect ratio with black bands on either the top
and bottom of the image (when viewed on a 4:3 display) or on the left and right sides (when viewed on a 16:9 display).
This maintains the display aspect ratio without distorting the image.
5 Choose an option from the Image Size menu to control whether the document pixels are scaled to the device
display:
Do Not Scale Applies no vertical scaling to the image. The image is cropped if its height is greater than that of the video
display.
Scale To Fit Within Frame Increases or decreases the image height and width proportionally to fit in the video frame.
With this option, a 16:9 image appears on a 4:3 display as letterbox, and a 4:3 image appears on a 16:9 display as
pillarbox.
6 Select the Apply Pixel Aspect Ratio To Preview check box to display the image using the document’s (nonsquare)
pixel aspect ratio. Deselect this option to display the image as it appears on your computer (square pixel) monitor.
By default, the Apply Pixel Aspect Ratio To Preview check box is selected to maintain the image’s pixel aspect ratio. In
general, you would deselect this option if the document’s pixel aspect ratio is assumed to be square and you want to
view the image as it would appear on a computer (square pixel) monitor.
7 Click OK to export the document to the device display.
