Specifying your A/V input settings

you want to capture to 1080i at 29.97 fps. For a list of the input and capture

formats that are supported on MXO2, and to view the MXO2 input scaling

options, see Appendix C, “Matrox MXO2 Supported Input and Capture

Formats.”

¦NoteIf Scale input for capture is not selected, your capture format must

match your source video’s format.

6 If you selected Scale input for capture in step 5, select the format of your

source video (MXO2 input) from the

Source format list:

¦NoteDepending on the input type selected in step 3, some options may not

be available.

$ SD 4:3 Select this option for standard 4:3 NTSC or PAL video. When

upscaling to HD, the video is captured in pillarbox format.

$ SD 16:9 Select this option for widescreen 16:9 NTSC or PAL video.

When upscaling to HD, the video is captured in anamorphic format.

$ 720p Select this option for 720p video.

$ 1080i Select this option for 1080i video.

$ 1080PsF Select this option for 1080PsF video.

7 If you selected Scale input for capture in step 5, select the Aspect ratio

formatting

option to be used when your source video’s aspect ratio does not

match the capture aspect ratio:

$ Letterbox/Pillarbox When capturing 16:9 video from a 4:3 source,

your video is captured in pillarbox mode (black bars to the left and right

of the picture). When capturing 4:3 video from a 16:9 source, your video

is captured in letterbox mode (black bars at the top and bottom of the

picture). When capturing 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 capturing 16:9 video from a 4:3

source, your video is captured in center zoom mode (picture is zoomed

with even cropping of the top and bottom edges of the picture). When

capturing 4:3 video from a 16:9 source, your video is captured in center

cut mode (even cropping of the left and right edges of the picture).

$ Anamorphic Captures the source video so that the entire picture fills

the capture aspect ratio, without cropping. The source video’s aspect ratio

is not maintained.
