KONA 3 cross-conversion allows you to convert from one format of HD to another, such as
1080i @ 29.97 to 720p @ 59.94. KONA 3 does not perform 2K to HD cross-convert, but can
display a cropped cut of the 2K on an HD monitor. In addition to HD-to-HD cross-
conversion, KONA 3 also can perform SD to SD hardware based aspect-ratio conversion for
capture and output. This is controlled the same as all other up/down/cross-conversions. Use
it by selecting a ‘Secondary Video Format’ that matches the ‘Primary Video Format’ and
then specifying the conversion using the ‘Convert Mode’ control.
