Press
Hue/Black Level
and use the
Hue Rotate
and
Black Level
knobs to adjust the hue and black
levels.
•
Hue Rotate
— increasing the hue rotation turns
the color wheel clockwise, and decreasing the
hue rotation turns the color wheel
counter-clockwise.
•
Black Level
— acts as a luminance offset and
moves the line towards the top left or bottom
right corner on the luminance graph.
9.
Press
Lum Gamma
and use the
Gamma Value
and
Gamma Offset
knobs to adjust luminance
gamma.
•
Gamma Value
— adjust the luminance gamma
control point.
•
Gamma Offset
— adjust the luminance gamma
offset of the control point.
RGB Color Correction
The RGB Color Correctors allow you to adjust the red,
green, and blue component gain, offset, and gamma of
the video signal.
To Apply RGB Color Correction to a Source
Both the
Input RGB Mode
menu and
Bus RGB Mode
menu work the same. The rest of this procedure shows
the
Input RGB Mode
menu, but the procedures apply
to both.
Tip:
You can revert the color correction back to the default
settings by pressing the Default X button for the component you
want to default.
1.
Double-press the source button for the input video
source, or bus, that you want to apply the RGB color
corrector to.
2.
Press
Input RGB
or
Bus RGB
to select the type
of RGB color corrector that is applied.
•
Input RGB
— input-based color correction. The
input BNC that is displayed on the menu is used.
•
Bus RGB
— bus-based color correction. The
ME and bus that is displayed on the menu is
used.
3.
(Optional: Input RGB Only) Use the
Color Gamut
buttons to set the color gamut of the source.
Tip:
If the color gamut or dynamic range differ from what
the switcher is operating in they will be converted.
Note:
There are restrictions on the types of HDR and color
gamut conversion you can do, and you can adjust the
scaling of the conversion. Refer to
(HDR) and Wide Color Gamut (WCG) Conversion
on page
83 for more information.
•
BT.709
— color gamut recommended for HD
video signals.
•
BT.2020
— wide color gamut recommended for
UHDTV1 video signals.
4.
(Optional: Input RGB Only) Use the
Dynamic
Range
buttons to set the dynamic range of the
source.
•
SDR
— Standard Dynamic Range.
•
HLG
— Hybrid Log Gamma.
•
PQ
— Perceptual Quantizer.
•
S-Log3
— Sony
®
S-Log3.
5.
Press
Red Adjust
,
Green Adjust
, or
Blue
Adjust
to adjust an individual color component, or
RGB Adjust
to adjust all three simultaneously.
6.
Use the
Gain
,
Offset
, and
Lower Offset
knobs
to adjust the selected color component(s).
•
Gain
— adjust the gain of the selected
component(s).
•
Offset
— adjust the offset of the selected
component(s). Offset moves the line towards the
top left or bottom right corner of the graph.
•
Lower Offset
— adjust the lower offset, lift,
of the selected component(s). The lower offset
moves the minimum point on the graph along
either the vertical axis or horizontal axis.
7.
Press
Red Gamma
,
Green Gamma
, or
Blue
Gamma
to adjust the gamma of an individual color
component, or
RGB Gamma
to adjust all three
simultaneously.
8.
Use the
Gamma Value
and
Gamma Offset
knobs
to adjust the gamma of the selected color
component(s).
•
Gamma Value
— adjust the gamma control
point of the selected component(s).
•
Gamma Offset
— adjust the offset of the
gamma control point of the selected
component(s). The gamma offset control point
value moves the control point along the graph
line and the gamma value alters how much
perpendicular offset is applied to the control
point.
Defaulting Color Correctors
You can default each color corrector element as you are
adjusting them, or you can default all the inputs or buses
that you have applied color correction to.
