Chapter 7, Configuring Your MXO2 System
at 23.98 fps project will be output as 486p, and a 720p at 25 fps project
will be output as 576p.
$ 720p Sets the main channel’s video output to 720p at a frame rate
compatible with your project’s video frame rate.
$ 1080i/PsF Sets the main channel’s video output to a 1080i or 1080PsF
format, depending on your project’s video format. For 23.98 fps video,
selecting this option outputs 1080PsF at 23.98 fps video by default.
However, you can use the
Pulldown feature (see step 5) to convert
1080PsF at 23.98 fps video to 1080i at 29.97 fps video at the output.
$ 1080p Sets the main channel’s video output to 1080p at a frame rate
compatible with your project’s video frame rate.
5 If 1080i/PsF was selected in step 4, select Pulldown to output 23.98 fps
video as 1080i at 29.97 fps video instead of 1080PsF at 23.98 fps. Matrox
uses standard pulldown to convert 1080PsF at 23.98 fps video to 1080i at
29.97 fps video. For a description of standard pulldown, see Appendix A,
“Understanding Pulldown.”
6 Under Channel Selection, select the video channel (main or SD) that you
want for your MXO2 analog (composite, S-Video, and component), SDI (not
available on MXO2 Mini), and HDMI outputs:
$ Main channel Outputs your project’s video as defined for the main
channel (see step 4).
$ SD channel Outputs your project’s video as NTSC or PAL, depending
on your project’s video output frame rate.
7 Under Channel Behavior, select the Aspect ratio formatting option to be
used for your video output when the source video’s aspect ratio does not
match the main channel/SD channel output’s aspect ratio:
$ Letterbox/Pillarbox When outputting 16:9 video from a 4:3 source,
the video is output in pillarbox mode (black bars to the left and right of
the picture). When outputting 4:3 video from a 16:9 source, the video is
output in letterbox mode (black bars at the top and bottom of the picture).
When outputting SD 16:9 from an SD 4:3 source, this option is not
supported and will result in anamorphic video.
$ Center cut/Center zoom When outputting 16:9 video from a 4:3
source, the video is output in center zoom mode (picture is zoomed with
even cropping of the top and bottom edges of the picture). When
outputting 4:3 video from a 16:9 source, the video is output in center cut
mode (even cropping of the left and right edges of the picture).
$ Anamorphic Outputs the source video so that the entire picture fills the
capture aspect ratio, without cropping. The source video’s aspect ratio is
not maintained. When outputting 4:3 video from a 16:9 source, select the
