Setup (NTSC) Use this to select the setup level you want for your
NTSC analog video. This affects both the NTSC analog video input and
output.
• 0 IRE Applies a setup level of 0 IRE. You should select this option
only when working with a commercial DV device that uses the
Japanese analog NTSC setup of 0 IRE. For example, if the video
appears too bright when you play back DV clips on your NTSC
monitor, you can change the setup to 0 IRE to output your DV clips at
the correct brightness.
• 7.5 IRE Applies the standard NTSC setup level of 7.5 IRE.
$
Aspect Ratio Conversion Use this to specify how you want your
video to be output when upscaling or downscaling:
• 16x9 Letterbox Outputs the widescreen 16:9 picture in letterbox
mode by adding black bars at the top and bottom of the picture for
display on a standard 4:3 television screen.
• 4x3 Pillarbox Outputs the standard 4:3 picture in pillarbox mode by
adding black bars to the left and right sides of the picture for display on
a widescreen 16:9 television screen.
• Anamorphic Outputs the widescreen 16:9 picture as horizontally
compressed 4:3 video, which retains the picture’s full vertical
resolution for display on a widescreen television. To display the video
with the correct proportions on an NTSC or PAL monitor, select the
16:9 display setting on the monitor.
• Center Cut Outputs the widescreen 16:9 picture by evenly cropping
the left and right sides of the picture for display on a standard 4:3
television screen.
• Center Zoom Outputs the standard 4:3 picture by evenly cropping
the top and bottom edges of the picture for display on a widescreen
16:9 television screen.

select Component , or Composite & S-Video if you’re outputting SD
analog video. If you’re outputting HD analog video, the output type will
be set to
Component (and the composite and S-Video outputs will be
invalid).
