KONA 3 Installation and Operation Manual — Using The KONA 3 Control
Graphic over Video In—places a graphics file having an alpha channel (chosen in
“Graphic File” pulldown) over the video input for playout or print-to-tape.
Graphic over Frame Buffer—places a graphics file having an alpha channel
(chosen in “Graphic File” pulldown) over the current contents of the KONA
card’s Frame Buffer (which might be from storage, video In, Kona TV, etc.).
Matte Color: only available when the pulldown “Frame Buffer over Matte” or
“Graphic over Matte” are selected-pressing this button brings up a color selection
dialog. The dialog provides a variety of ways to select a matte color including a
color wheel, color picker (choose from a location anywhere on the computer
screen), numeric sliders, swatches, “crayons”, and spectrums. The matte chosen
will be used as a video background under the keyed video.
Foreground pre-multiplied (checkbox): use to avoid “matte lines” and improve the
appearance of the foreground (key) being composited over the background.
Audio Out:
Frame Buffer—select audio out to be routed from the contents of the Frame
Buffer.
Audio In—select audio out to be routed from KONA’s currently selected
input(s).
Opacity: this slider controls the transparency of the keyed video (over the
background) from translucent to completely opaque.
Graphic File: this pulldown allows you to choose from any recently accessed file or
select a new file (“Load File...”), which then brings up a file dialogue. Remember
that the file raster (pixel x pixel count) should match the primary format in the
frame buffer or the secondary format if upconverting. Example: you wish to key a
logo on top of your 1920x1080 footage, the still image with alpha channel that
you load should be 1920x1080.
