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 are working with progressively segmented
frame formats (sf in the AJA Control Panel) as compared to progressive frame
formats which will show only “p.”
Crossconversion:
if you have an HD format as your primary and then select a
secondary HD format with a different frame size, the Io HD will perform a
crossconversion where necessary (input or output) for “
like Hz”
formats. By
like
Hz
this means that 720P 59.94 may be converted to 1080i 29.97 (59.94Hz).
Converting from disparate Hz is not supported on the Io HD for
crossconversions. The example below shows 1080i to 720p.
