Adjusting an UltraChrome Chroma Key in Basic Mode
Adjusting the values of a Chroma Key can be done at any time after you have initialized the Key. The
following procedure assumes that you have already created and initialized the Key in Basic Mode and
are attempting to improve the appearance of it.
An UltraChrome Chroma Key, when created in Basic Mode, enables you to adjust the following
parameters:
• Background — Background elements are those areas in the source video that are the
same color as the one you chose to key out.
• Foreground — Foreground elements are those pixels that are not within the
Background ranges. This is the area with colors that will not be keyed out and will
remain solid.
• Spill Suppression — Spill Suppression elements are those areas in the Foreground that
have a noticeable tint of the Background color. This typically occurs around the edges of
subjects as glow from the background blue or green-screen “spills” onto them. Adjusting
this parameter will correct the amount of blue or green spill.
• Edge Softness — Edge Softness lets you apply varying degrees of softening to the
foreground edges to help it blend in with the underlying background image.
You can use the knobs in the Mattes Group or the Positioner on the Synergy control panel to adjust
the for adjusting the UltraChrome Chroma Key parameters as follows:
• Move the Positioner left or right (X-Axis) instead of the
Hue
knob
• Move the Positioner up or down (Y-Axis) instead of the
SAT
knob
• Move the Positioner clockwise or counter-clockwise (Z-Axis) instead of the
LUM
knob
Use the following procedure to adjust your UltraChrome Chroma Key in Basic Mode:
1. Create an UltraChrome Chroma Key as described in the section “ Creating an
UltraChrome Chroma Key in Basic Mode ” on page 7-14.

3. Press 2. Background to display the Background Menu .
Note Every time 1. Initialize Key is pressed, the switcher will reset all the
Chroma Key parameters to their optimal default values for the video.
