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 a Matte setting is selected above, 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 Load (LHi Only)
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.
