Io HD Installation and Operation Manual — Using The AJA Control Panel
Video Setup
Tab Screen Io HD provides a high-quality analog component or composite output, generally used
for monitoring. This screen shows the current settings for that analog output, and
allows you to re-configure it when desired.

Analog Black Level —choices in the black Level pulldown menu are only available for
the two Composite analog formats. Choices presented are for US or Japan:
7.5 IRE (NTSC US)
0 IRE (NTSC Japan)
QuickTime Video Output Display Filter —this filter is designed to help manage the
comprehensive list of video outputs that may be available to applications,
particularly Final Cut Pro's A/V Devices tab. By selecting a checkbox next to a
desired parameter, the video outputs related to the specified parameter are
enabled as possible video outputs for applications. As an example, if the checkbox
next to
25/50 is unchecked, 50Hz video outputs are deselected and would not be
available to the user in the A/V Devices tab of Final Cut Pro. To avoid confusion
when working in a particular editorial environment, users might elect to leave
50Hz unchecked if they work solely in a 60Hz editorial environment. The same
might be true for users who do not intend to work with true progressive 1080
material (
Progressive checkbox).
Note: If a prompt occurs in Final Cut Pro stating that the AJA output device is
missing, this simply may be due to the Active Video Filter for a given parameter being
unchecked for the format being selected in the application. If this occurs, simply
make the appropriate selection in the Control Panel application and re-enter Final
Cut Pro where the selection should now be available.
