Introduction
This quick reference guide provides information related to the greenMachine HDR Static initial setup and configuration. The greenMachine
HDR Static, 1 RU half 19” rackmount, is a real-time broadcast-quality HDR to SDR, SDR to HDR, or cross-standards HDR to HDR
converter with frame sync supporting formats up to 4K UHD (3840x2160). HDR Static applies color and contrast parameters equally
throughout a specific piece of content, i.e. an average brightness/color range is determined across an entire program.
HDR Static greenMachine processor has an advanced algorithm that overcomes the issues arising from “round-tripping” SDR>HDR>SDR.
The SDR signal at the production end and the distribution end of the round trip are visually identical, making the whole SDR>HDR>SDR
conversion process transparent. Supporting 4 x 3G or 1x 4K/UHD processing channel, HDR Static provides up, down, and cross-
conversions in HDR and SDR curves through appropriate static tone mapping. It also supports Wide Color Gamut (WCG) needs of
broadcasters, and professional AV live events requirement. HDR Static is most suitable for the environments outdoor/ indoor where the
light conditions do not change dynamically.
This Quick Reference Guide is designed to help you setup greenMachine HDR Static and provides the step-by-step instructions to
configure your HDR Static constellation to achieve the best possible up/down/cross conversion between HDR and SDR for your
operations. For additional information, please refer to the “HDR Static Reference Manual.”

3. IP Network Settings
The greenMachine is a networked device and may require network settings for it to be connected to the network. By default, the
IP setting of the greenMachine is set to DHCP. If the network to which greenMachine is connected uses a DHCP server, then the
greenMachine will automatically capture the IP address and other settings. The greenMachine will appear on the greenGUI.
If the network to which greenMachine is connected to does not have a DHCP server, then configure the IP settings manually from
the front panel of the greenMachine as shown in the steps as below:
Press the “System” button to access the Menu
Using the rotary knob, highlight “IP settings” and press to enter
Highlight IP mode and rotate the knob to select “static” in the middle
of the screen and press to enter (default is DHCP mode).
Using the menu system and rotary control, make the required
manual numeric entries for the IP address, Gateway, and Netmask.
Please ask your network/IP support for the settings if needed.
Note : The values given in the pictures above are for demonstration purposes only.
Once IP settings are completed, exit the IP setting menu. The greenMachine will now be visible on the greenGUI
running on your PC or MAC.

signal is transparently passed through the system.
Note: In this mode, only “colorimetry” and “range” conversion of SDR signals can be
performed.
STATIC:Selecting this option activates the actual operation of HDR STATIC
constellation. It allows the user to perform up/down/cross conversion between HDR
and SDR.
Custom LUT: The Operation Mode “Custom LUT” allows users to select their own
LUTs to obtain the desired contrast, color, saturation, black and white levels. Users
are provided with 20 slots to upload up to 20 custom LUTs.
For more information on the Operation mode, refer to the HDR Static Reference
manual “Operations Mode.”
Presets
There are several useful presets provided for quick operations. The following presets
are available to the user for selection:
Input
Input Transfer
Characteristics
The following input transfer characteristics are provided: SDR, HLG, PQ-ST2084, PQ-
BT2100, Slog3, Panasonic V-log, Arri LogC, RED Log3G10, Canon C-Log2, BMD
Film
For more information on Transfer characteristics, refer to HDR Static reference
manual “Transfer characteristics.”
Input Colorimetry
The following Colorimetry is provided: BT.2020, BT.709, Sony S-Gamut, ACES, DCI-
P3, Panasonic V-Gamut, BMD Film, Canon Cinema Gamut, Arri Alexa, Red Wide
Gamut
For more information on Colorimetry, refer to the HDR Static reference manual
“Colorimetry / Gamut.”
Input Range
The following input range is provided: Full, Narrow, and Auto
Full: Full Range is the complete range of bits used for representing blacks and
whites. For example, in a 10-bit signal, 0 bit represents the black, and 1023 bit
represents the White.

Narrow: Narrow Range is the limited range of bits used for representing black and
whites. For example, in a 10-bit signal, 64 bit represents the Black, and 940 bit
represents the White.
Auto:In this mode, the system reads the VPID information on the signal to determine
the “Narrow” or “Full” range.
For more information on range, refer to the HDR Static Reference manual “Signal
Range.”
Mapping
Mapping Type
The tone mapping operation can be performed with two possible approaches
depending on the user cases:
1. Tone Mapping Scene Light
2. Tone Mapping Display Light
3. Direct Mapping Scene Light
4. Direct Mapping Display Light
Tone Mapping is preferred for up-and-down conversion for mapping cameras. In the
case of up-conversion, when the intent is to create a stronger HDR look and in case
of down conversion when the intent is to preserve more contrast, then the Tone
Mapping technique is preferred.
Direct Mapping is used when the intention is to preserve the SDR content and make
up-converted HDR look identical to the original SDR version, or to make the signal
from HDR camera look similar to the signal delivered by an SDR camera operated
without a “knee” function.
Scene Light mapping is used when the goal is to match the colors and relative tones
of HDR and SDR cameras.
Display Light mapping is used when the goal is to preserve the colors and relative
tones, as seen on a reference display.
For more information on Mapping, refer to the HDR Static Reference manual
“Mapping.”
Output
Output Transfer
Characteristics
The output transfer characteristics provided are SDR, HLG, PQ-ST2084, PQ-BT2100,
Slog3.
For more information on Transfer characteristics, refer to HDR Static reference
manual “Transfer characteristics.”
Output Colorimetry
The following output colorimetry is provided: Rec 709, Rec 2020, and Auto
Note: In Auto mode, the output follows the input, and no conversion takes place
For more information on Colorimetry, refer to the HDR Static reference manual
“Colorimetry / Gamut.”
Output Range
The following output range is provided: Full, Narrow, and Auto
Full: Full Range is the complete range of bits used for representing blacks and
whites. For example, in a 10-bit signal, 0 bit represents the black, and 1023 bit
represents the White.
Narrow: Narrow Range is the limited range of bits used for representing black and
whites. For example, in a 10-bit signal, 64 bit represents the Black, and 940 bit
represents the White.
Auto:In this mode, the output follows the input, and no conversion takes place. For
example, if the input range is “Narrow,” then the output range will be “Narrow.”

For more information on range, refer to the HDR Static Reference manual “Signal
Range.”
Select Processing in the HDR Static tab and adjust the
parameters as required
(Check description of each parameter below)
Check the description of each parameter in the HDR Static > processing page
For detailed information on processing parameters, refer to the HDR Static reference manual “Processing
Parameters.”
Setting
Description
Gain
This parameter is used to adjust the luminance of the overall image. The default value is set
to 0.00 dB and leaves the image unchanged, whilst a value less than 0.00 dB reduces the
brightness, and a value greater than the default value increases the brightness of the image.
Note: Higher value can lead to flattening of the image impression.
+12.00 dB: Extremely increased brightness
00.0 dB: Unchanged
-12.00 dB: Extremely decreased brightness
Default Value: 0.00 dB
If the image appears too dark, e.g. after an SDR-to-HDR up-conversion, a luminance gain can
be used to adjust the image and achieve better matching to the luminance of native HDR
material. This processing can be undone in case of “round-tripping” if the inverse value is
used for the reverse conversion.
Saturation
Due to the contrast conversion and a possible gain adjustment, the brightness component of
the image is altered. The change in the brightness affects the color impression, such as
saturation. If the saturation impression does not match the expectation, then the “saturation”
parameter offers the possibility in adjustment. The default value is set to 1.0, which leaves the
saturation unchanged.
2.0: Extremely increased saturation
1.0: Saturation unchanged
0.0: Extremely reduced saturation
Default Value: 1.0
Select Custom LUTs in the HDR tab to import, export and
set parameters for the Custom LUT.
For more information on Custom LUTs, refer to Custom LUTs Quick
Reference Guide.
