KONA LH Capture, Display, Convert v14.3 28 www.aja.com
RGB Range
The RGB Range pulldown menu allows you to select either Full-range (0-1023) or
SMPTE range (typically 64-940) for RGB color output.
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 recognize:
• “sf” for progressively segmented frame formats
• “p” for progressive frame formats
Follow Input
Enabling the Follow Input checkbox allows the Control Panel Buffer to auto-
switch to whatever is the detected input format. This feature works only if the
controlling application supports input-based capture—AJA Control Room for
example.
Format Conversions
Cross-Conversion
If you have an HD format as your primary and then select a secondary HD
format with a different frame size, KONA will perform a cross-conversion where
necessary (input or output) for “like Hz” formats. “Like Hz” means that 720P 59.94
may be converted to 1080i 29.97 (59.94Hz). The example below shows 1080i to
720p.
Up Conversion
The Up and Down pull-down menus are available when conversion has been
selected for the video path to/from the framebuffer and like Hz formats are
selected (the one exception is 1080PsF 23.98 which can be down-converted
to 525i 29.97.) Different choices will be available depending on the type of
conversion and formats being converted. SD to SD conversions are essentially
aspect ratio conversions to accommodate transforming anamorphic images to
letterbox or vice versa.
For up-conversion the following choices are available:
• Anamorphic: full-screen “stretched” image
• Pillar box 4:3: results in a 4:3 image in center of screen with black sidebars
• Zoom 14:9: results in a 4:3 image zoomed slightly to fill a 14:9 image with black
sidebars
• Zoom Letterbox: results in image zoomed to fill full screen
• Zoom Wide: results in a combination of zoom and horizontal stretch to fill a
16:9 screen; this setting can introduce a small aspect ratio change
Down Conversion
For down-conversion the following choices are available:
• Letterbox: image is reduced with black top and bottom added to image area
with the aspect ratio preserved
• Crop: image is cropped to fit new screen size
• Anamorphic: full-screen “stretched” image
