Format Screen
The Formats screen shows the video format currently in use by the Io XT framebuffer
(called the Primary Format) and allows you to change it. All throughout the Control Panel,
choices are always presented based on what Io XT can do with the signals available and
the inputs/outputs selected. For example, on the Format screen, if the output or inputs
are a different format than the primary, then you’ll see an additional information pane
that allows you to view and edit the secondary format—including control over whether
up/down/cross conversion is employed.

Video Format (Primary and
Secondary):
These pull-down menus show the currently selected formats. If you select an alternate
value in the Primary Format using the pull-down, it will change the format used by Io XT's
framebuffer. When a change is made via the Video Format pull-down or by clicking an
icon (widget) and selecting a new format via a contextual menu, the block diagram will
change to reflect the new format. In the case of a Secondary Format, the formats
available can vary based on what the Primary Format is and the input signal (frame rates
of input sources limits the to/from conversion choices). The “Secondary Video Format”
pull-down menu lists all compatible formats for selection (incompatible formats are not
shown). This allows you to see what you've chosen, and also see those formats that are
compatible with the selected Primary format.

NOTE:
The AJA Control Panel software uses the abbreviation “sf” instead of “psf” when referring to
“progressive segmented frame” formats. In the manual and in other literature you may see
either of these acronyms used interchangeably. Visually it is easier to discern at a glance if you
