thresholds much above black will affect dark grays that are actually part of the foreground
subject, making the chroma key composite look unnatural.
Fringe is used to restore color to the gray portions of the foreground color resulting from
secondary suppression adjustments. This control is only active when secondary
suppression is on.
Shdw provides controls of shadows that fall on the backing. Shadow Clip and
Shadow Gain allow selecting the range of the luminance portion of the foreground that
produces a shadow. Shadow Density is an opacity control for the shadow and adjusts how
much shadow is added to the background.
Setting Up a Chroma Key
Configure Auto Setup
1 Press one of the keyer transition buttons on the Control Panel (for example Key 1 ) on an
M/E to delegate the keyer you wish to use.
2 Choose the selected keyer’s key bus that has the chroma key source and the chroma
key backing color.
3 Select the CHR as the key type in the Multi-Function Module (source memory may
automatically select this key type).
4 Choose the source on the A bus that will be used to replace the backing color of the
chroma key source.
5 Go to the Keyer menu either by double pressing a keyer transition button on the
Control Panel (for example Key 1 ) or selecting Keyer, Mode on the menu and make
sure Reshape is off for the keyer you are using.
6 Press the Auto Setup button on the Control Panel or select it in the menu. Preview for
that M/E will now display the chroma key source with a superimposed cursor. The
cursor actually represents a box of 16 x 16 pixels.
