Keyer

Key/fill controls described below only appear on devices with +KEYER licensed optional feature. This feature
requires a rear panel port that accommodates separate key/fill video inputs. Note that on devices also licensed with +KEYER, Wings
and Keyer controls appear on the same tab.
Note:
Keyer tab has identical independent controls for both Path 1 and Path 2 using the Path 1 / Path 2 sub-tabs. Therefore,
only the Path 1 controls are shown here. Set controls for other path using the respective sub-tab.

Displays wings timing status as described below.
Note: • Wings timing is a function of the wings frame sync card/
device. Ideal wings timing is within 0 to 200 samples early
of output video timing. Wings timing cannot be controlled on
host device wings inserter.
• Error in wings timing will result in loss of wings (however,
program video image will not be corrupted).
Provides key/fill insertion controls and displays insertion
status.
Selects the SDI input video ports to serve as the key and fill sources.
Note: • SDI inputs selected must be used with Rear I/O Module
correspondingly equipped with intended input ports.
• Other key/fill input choices sourced from Path 1 and Path 2
program video outputs also are available using this drop-down.
These selections are not typically used for normal use. A white
paper describing these use cases may be developed in the
future that explains the use of special looping alternate-path
inputs. In brief, these alternate inputs are useful for providing
two identical video paths with a delay offset provided by the
second path.
Selects key mode as follows:
• Alpha Ramp setting is used when typical key/fill is provided by key/fill
generator with separate key and fill outputs.
• Alpha Threshold or Reverse Alpha Threshold setting is used to
provide keying using a combined key/fill signal derived from a simple
graphic source.
Key Enable control sets up key/fill for insertion. When enabled, key
preview is available on Key Preview output.
When key preview shows desired results, Apply Key To Program can be
enabled to apply the key/fill to the program video output.
