Choose the Gamma Curve option from the drop-down menu. The selection
characterizes the video signal on each virtual input.
– Auto: The system selects the setting based on ST352 VPID. If ST352 VPID is not
present, SDR Narrow is selected.
– SDR Narrow: The reference OETF (Optical to Electrical Transfer Function) is
defined in ITU-R BT.709 with gamma of 0.45 and the reference EOTF is defined in
ITU-R BT.1886 with gamma of 2.4.
The Narrow scaling places the extremes of the nonlinear color value from zero to
unity at code words 40 hex (64 dec) and 3AC hex (940 dec) in a 10bit
representation for 0% Black to 100% White. This range is typical for standard-
dynamic range.
– SDR Full: The reference OETF (Optical to Electrical Transfer Function) is defined in
ITU-R BT.709 with gamma of 0.45 and the reference EOTF (Electrical to Optical
Transfer Function) is defined in ITU-R BT.1886 with gamma of 2.4.
The full scaling places the extremes of the nonlinear color value from zero to
unity at code words 0d and 1023d in 10bit representation and 0d and 4095d in
12bit representation for 0% black and 100% white, respectively.
– PQ Narrow: The reference OETF with a high luminance range capability of 0 to
10,000 cd/m2 standardized in SMPTE2084. The EOTF is the inverse of OETF.
The narrow scaling places the extremes of the nonlinear color value from zero to
unity at code words 40 hex (64 dec) and 3AC hex (940 dec) in a 10bit
representation for 0% Black to 100% White. This range is typical for standard-
dynamic range.
– PQ Full: The reference OETF with a high luminance range capability of 0 to 10,000
cd/m2 standardized in SMPTE2084. The EOTF is the inverse of OETF.
The full scaling places the extremes of the nonlinear color value from zero to
unity at code words 0d and 1023d in 10bit representation and 0d and 4095d in
12bit representation for 0% black and 100% white, respectively.
– HLG: The reference OETF is standardized in ARIB B67 and the reference EOTF is
standardized in ITU BT.2100 at the nominal display peak luminance of 1000 nits.
– S-Log2: The reference OETF is defined as Sony S-Log2. The EOTF is the inverse of
OETF.
– S-Log3: The reference OETF is defined as Sony S-Log3. The EOTF is the inverse of
OETF.
– S-Log3 (Live HDR): The reference OOTF (Optical to Optical Transfer Function) is
defined as Sony S-Log3.
– Log C: The reference OETF is defined as ARRI Log C. The EOTF is the inverse of
OETF.
Note: The Structure option is set to Auto.
