$ Letterbox Captures the widescreen 16:9 picture as letterbox video by
adding black bars at the top and bottom of the picture for display on a
standard 4:3 television screen.
$ Center cut Captures the widescreen 16:9 picture for display on a
standard 4:3 television screen by evenly cropping the left and right edges
of the picture.
$ Anamorphic Captures 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.
Specifying your video output settings
This section specifies the video output settings for Matrox MXO2, MXO2 Rack,
and MXO2 LE. For MXO2 Mini, see “Specifying your video output settings
(MXO2 Mini)” on page 66.
MXO2 features simultaneous video outputs that allow you to send your video to
a variety of devices at the same time. MXO2 provides two separate video output
channels to choose from: main channel and SD channel. The video output
settings allow you to set the main channel’s video format, assign a video channel
to an MXO2 output, and define the channel’s behavior. You can also select other
settings such as the scrub and pause method, and calibrate your HDMI monitor
for video.
For a list of the supported video output formats for the MXO2 main and SD
channels, and the supported video formats for the MXO2 outputs, see Appendix
D, “Matrox MXO2 Supported Output Formats.”
