Analog Black Level
(in Io XT only):
Choices available for Black Level are the two Composite analog formats. Choices
presented are for US or Japan:
• 7.5 IRE (NTSC US)
• 0 IRE (NTSC Japan)
Progressive Formats: Radio buttons allow you to choose between psf (progressive segmented frames) and p
(progressive frames) non-interlaced output.
QuickTime Video Output Filter
(available on Mac OS only):
The QuickTime Video Output Display Filter is designed to help manage the
comprehensive list of video outputs that may be available to applications.
By selecting the checkbox next to specified parameters, the video outputs related to
these specified parameters are enabled as possible video outputs for applications. For
example, if the checkbox next to 25/50 is unchecked, 50Hz video outputs are deselected
and would not be available to the user’s editing application. To avoid confusion when
working in a particular editorial environment, you might choose to leave 50Hz
unchecked if working solely in a 60Hz editorial environment. The same might be true if
you do not intend to work with true progressive 1080 material.
