SDI Output Options
Primary:
When selected, this indicates that the SDI output is set to the same format as the
framebuffer. That value will be listed in blue.
Secondary:
When selected, this indicates that the SDI output is set to a format different from the
framebuffer (Primary Format). That secondary format value will be listed in green. This
shows that active processing of the video is taking place (format change and possibly
even up/down-conversion).
Video+Key:
When selected, this indicates that the SDI 1 Output video is set to the same format as the
framebuffer. SDI 2 Output is set to a video key signal associated with SDI 1 (the shape to
be cut out from the video - this will appear as a black and white image/matte). Using the
second Io XT output as an Alpha Channel key, with the video output, may be useful for
feeding production switchers, DVEs or other professional video equipment.
