7.2.3 SE-1200MU’s Color Spill Settings
The Color Spill parameters and values are shown along the bottom of the display below. These
settings are used to control/remove any unwanted Chroma or color Spill from the background onto
the foreground subject. There are two sectors drawn on the Chroma palette, one represents the
wider Chroma Acceptance range and the narrower Chroma Suppress range.
Chroma Acceptance sets the amount of the available color range or space that should be Chroma
suppressed. Usually starting with a large value of 120 degrees should produce reasonable results. This
value can then be fine-tuned up or down using the Chroma Acceptance value depending on the setup
of your green or blue screen studio.
Chroma Suppress, when set to 0%, removes the hues or colors that lie only on the same axis as the
Chroma Matte Hue angle. This setting has the effect of removing Background color spill, but keeping
the underlying hue. When set to 100% then all the Chroma values that are ‘captured’ within the
Chroma Acceptance Angle are suppressed to greyscale – i.e. they have their Chroma removed.
Usually starting with a value of 50% should produce reasonable results. This value can then be fine-
tuned up or down using the Chroma Suppress value depending on the setup of your green or blue
screen studio.
Saving the Chroma Key Setup. Remember to save your current user setup. In this way, several
Chroma Key setups can be saved to different user memory slots, thus allowing you to switch from a
Blue screen setup to a Green screen setup instantly.
