When a chroma key layer
is applied to an effect production element, for example a mix or other background (created in GV
Director Composer), the GV Director system provides runtime adjustment of chroma key values to
improve the quality of the key for lighting and consistency of the matte (environment can affect
the chroma key for example in a dynamic environment with live inputs, changing light, and
possibly a subject in front of a green screen).
A chroma key layer must have been added when the
effect was created for the adjustments to have any affect.
