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.
