(continued)
Displays keyer timing status as described below.
Note: • Key/fill timing is a function of the respective key and fill signal
frame sync card/device(s). Ideal timing is within 0 to 200 samples
early of output video timing. Key/fill timing cannot be controlled on
+KEYER host device.
• Error in key/fill timing will result in loss of keying (however,
program video image will not be corrupted).
When keying is set to Alpha Threshold or Reverse Alpha Threshold mode
sets luma thresholds, when crossed, allow key/fill onto program video
image.
Key Alpha setting, when increased, increases the opacity of the key/fill.
Key Threshold setting, when reduced, more readily allows the key/fill
input to assert itself over more variations of program video luma levels.
