Copying mattes
The adjustments of a matte can be easily copied into another matte:
•
Press Input Corr; the key lamp lights.
•
Select with Matte sel or BGD matte the matte you want to copy.
•
Press Matte 1 or Matte 2 and hold the key down.
•
Select with Matte sel or BGD matte where you want to copy the adjustments
to.
•
Release Matte 1 or Matte 2.
2.9.1 LIMITATION OF THE COLOR TRIANGLE
The new color triangle limitation (as from software version ”F”) controls the effects
of MATTE settings on
D
RGB color triangle
D PAL/NTSC level
It ensures that these limitation regulations are observed but also that the scope is
fully exploited. Both regulations are applicable at all times with the stricter regula-
tion prevailing on a case by case basis.
These signals are derived from ME1.
RGB limitation All colors are permitted that do not produce an R, G or B level of > 100% or <0% (this
means that about 75% of all conceivable Cb/Cr/Y combinations are not permitted).
PAL/NTSC limitation All colors are permitted as long as the total of luminance and chrominance does
not exceed the (adjustable) COL LIMITER level.
If COL LIMITER is set to 133, a PAL/NTSC overlevel of 33 % will admissible but the
representation of all RGB values (including a saturated yellow) will be possible. If
COL LIMITER is set to 100, a 100 % level will be ensured but certain (yellow) colors
will be inadmissible.
Function If in a modification of hue, chroma, or luminance one of the limits is reached, the
switcher sends a BEEP signal (can be disabled) and attempts to realise the
demanded value at the expense of a different parameter.
D
A change in HUE may result in a chrominance correction.
D
A change in CHR may result in a luminance correction.
D
A change in LUM may result in a chrominance correction.
If an absolute limit is reached, no value will change any longer. A maximum chroma
may generally be achieved at a medium luminance, i.e. subsequent decreases or
increases in LUM will result in a reduction in chrominance.
Limit mode ON/OFF The limit mode simplifies the search for colors with maximum saturation. This mode
is enabled, when chrominance is set to maximum.
In subsequent HUE changes, the color follows lines of maximum saturation. For
this purpose, both chrominance and luminance are continuously updated automat-
ically. If the chrominance or luminance setting is changed, this mode is disabled
again.
