2.8.4 POSITIONING SIZING SOFTENING P/S/S
These three functions are available in the Lum/Add key and FG Fade modes, not
in the DynaChrome.
Attention: When selecting P/S/S in the DynaChrome mode, the chromakey pro-
cedure automatically switches to FG Fade (quality loss)! When se-
lecting P/S/S in the Lum Self Key mode, the fill linearization is auto-
matically ommitted for the luminance key procedure (quality loss)!
All P/S/S parameters are stored in the KEY MEMORY, independent of the key type.
With RESET, all P/S/S parameters are reset. When starting an automatic key ad-
justment (AKA), all P/S/S parameters are switched to OFF, but will be preserved.
The setting range amounts to +/ – 8 pixels with a smallest increment of 1/8 subpixel.
A positive Positioning shifts the key signal with regard to the fill signal to the right.
The setting range amounts to +/ – 8 pixels with a smallest increment of 1/4 subpixel
with all permitted key types. A positive sizing extends the key signal, thus reducing
the foreground objects. By this way, incorrect object edges can be removed. How-
ever, foreground details will also disappear more and more.
A negative sizing increases the foreground object around the object edges. Dark
or key-colored object edges are added.
The key signal is filtered with an adjustability of 10 steps. Object edges and details
are softened.
