2.8.6 SELECTIVITY MASKING
The menu is available with the two chromaKey modes DynaChrome and FG Fade.
Thus, it is possible to select inside a mask area another selectivity than outside the
mask. This means, when – due to color conflicts within the picture – no compromise
can be found between the density of foreground objects of a certain color and the
freedom from fringes of other objects with the same color, the relevant objects can
be separated by the mask.
The separation lines remain invisible in the areas of the background. With correct
adjustment, they also remain invisible in the areas of the foreground. Only mixed
colors at the object edges are then affected.
Method of procedure (only with critical patterns):
D
AKA run AUTO or CURS/AUTO
D
First manual optimization of SEL L or SEL R. Purpose is the object density.
D
Adjustment of SEL C, DENSITY and CLEAN UP
If no satisfactory result:
D
Call from the Key menu of the SEL MSK (mask menu) and selection of the
Mask Source
D
Check in the PVW position of the mask
D
Call the automatic selectivity adjustment S–AUTO or call the menu Chroma
Adjust and manually adjust Selectivities–I (inside the mask) and Selectivi-
ties–O (outside the mask).
