Setup Screen Settings
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 settings:
•
7.5 IRE (NTSC US)
•
0 IRE (NTSC Japan)
Lock Audio Gain To Unity
—When set, Io Express will ignore the Final Cut Pro gain setting
and set the audio gain at unity. When not set, this checkbox tells Io Express to get the
audio gain setting from Final Cut Pro.
Analog Audio Monitor Level
—determines the audio level that will appear at the Analog
Audio Output RCA connector pair (“FSD” is
full-scale-deflection
reading as measured on a
VU meter). 18 for Europe or +24 for USA.
Active Video Output Filter
—The Active Video Output 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 the checkbox next to specified parameters, the video outputs related to
these specified parameters 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, users might elect to leave
50Hz
unchecked if they work solely
in a 60Hz editorial environment. The Quicktime application must be quit and restarted
to see changes here.
Note:
If a prompt occurs in Final Cut Pro stating that the AJA output device is missing, this
may simply be due to the Active Video Filter for a given parameter being unchecked for
the format selected in the application. If this occurs, quit Final Cut Pro, make the
appropriate selection in the Control Panel application and restart Final Cut Pro where the
selection should now be available.
