Lum Key Lum Key selects the luminance key mode. The key control signal is derived from
the luminance component of the key source signal. The key control signal controls
the transition between background signal and fill signal.
Luminance Key is available in the modes equalized (eq) and non-equalized.
Lum Key eq Is automatically switched on in the Self Key mode
(key fill signal corresponds to the key source signal).
Thus, dark halo effects at edges and soft transitions are
avoided.
Lum Key Is automatically switched on when Fill and Source do not
have the same source (Non Self Key).
Note: On American linear key.
Lin Key Pressing the two keys (Add) Lin and (Lum) Lin sets the luminance key into a linear
mode. The key control signal corresponds to the non- amplified and unlimited lumi-
nance signal.
Chr Key Chr Key selects the chroma key mode. The key control signal is derived from the
chrominance component of the key source signal. Keying is possible on each color.
The DynaChrome Key mode ensures that all details in the fill signal will be preser-
ved in accordance with the original.
Note: Please note that P/S/S = ON forcibly switches over to FGD–Fade.
FGD Fade When the Foreground Fade function is enabled, the key in control signal serves to
fade between the background signal and the cleaned key fill signal.
Note: Please note that DynaChrome can only be used without Foreground
Fade for Self Key (identical fill and source signal). If you are not working
with Self Key or in case of a border, Foreground Fade will automatically
be switched on without special indication.
Pattn 1, Pattn 2 Pattn 1 or Pattn 2 selects the wipe generator as a key source (pattern key). The
pattern can be selected with the pattern selection keys on the Wipe panel. The size
of the pattern can be adjusted with the Size control.
Positioning of the pattern is possible with the trackball on the Positioner panel. For
this purpose, previously press Pos on the Wipe panel.
Note: Please note that the wipe generators can be used at the same time for
different applications which may interact with one another.
