LiveGrade - User Interface Overview
In Figure 1 you can get an overview of LiveGrade’s main window and its different groups of controls.
Figure 1: LiveGrade PRO’s Main window
With the Project Manager you can switch projects. With projects you can manage grades
independently.
In the Grade Library you can save, recall and manage grades in groups. A list of preset grades is
available. For more information see The Grade Library.
The Grade History stores applied Grades and your modifications for later re-use. If you want to return
to previous grading settings just select the appropriate item in the History panel and click the “Apply”
button. The grade settings within the grading window will be reset to the according state without directly
affecting any grade in the Grade Library.
The Slot Selector lets you manage up to three devices together (LiveGrade Pro version). These devices
can be configured in the Device Manager. Each slot displays the grade currently applied to it. In
addition, it’s possible to show the original signal, by-pass color and apply False Color with the buttons in
every slot.
The Mode Selector lets you chose between the CDL, Alexa Looks and ACES grading modes. Depending
on the grading mode, the Grade Controls as well as the filtering of the image will change.
For more information see Grading Modes in LiveGrade.
The Grade Controls allow to interactively and creatively manipulate the colors of an attached SDI
stream. They can be resized by dragging the separation bar between the Grade Library and Grade
Controls. The Grade Controls consist of:
filter panels with Color Controls and
filter Order Controls (CDL Grade mode only)
The Toolbar lets you enable and disable certain image filtering steps and access to additional tools such
as the Cube-o-Scope.

Device Manager
For a successful and satisfying work with LiveGrade it is important to know how to manage all those
devices involved in your workflow. To simplify that task LiveGrade has a Slot Selector (figure 1). You will
be able to use it to apply grades to multiple devices at the same time (LiveGrade Pro). Open the Device
Manager (figure 1 #1) in the lower left corner of the LiveGrade application window to manage the
connected devices. In addition, the Slot Selector displays useful information such as the applied grade
(figure 1 #3) and the device connection status in green/orange for online/offline devices (figure 1 #4).
Finally, the image filter buttons (figure 1 #5) will let you switch each slot to the graded signal, original
signal, bypass color or False Color.
figure 1: LiveGrade User Interface – slot selector
The Device Manager recognizes the devices connected to your computer (figure 2) and lets you group
them into different slots. It’s possible to name each slot to easily recognize it in the Slot Selector. Slots can
be created with the «Add Slot» button (figure 2 #6) and deleted with the «Delete Slot» button (figure 2
#7).
To add a connected device to a slot you can just drag&drop it. Click on the «Add Device» button (figure 2
#1) to add a CDL server or setup a Pluto device . To set device specific options click on the «Config…»
button (figure 2 #2).
Each device can be color managed with ICC profiles (figure 2 #8) or specify if the in- and outgoing signals
need to be converted to Legal or Extended (figure 2 #5). To refresh the ICC profile list click on the
«Refresh ICC Profiles» button (figure 2 #3).

LiveGrade Pro Manual
HD-SDI Device Management
figure 2: LiveGrade Pro Device Manager
By clicking the «Blink» button (figure 2 #9) you can recognize which device in the Device Manager refers
to each input device. A click on that button causes a simple visual signal to your output device.
With the buttons at the bottom of the Device Manager (figure 2 #4) you can refresh the application for
recognizing new connected devices and new ICC profiles.
HD-SDI setup for LiveGrade
To properly setup your HD-SDI viewing environment with LiveGrade there are some things to consider
depending on your setup. The following figure shows an example of a setup with a HD-SDI signal coming
from a camera going to a monitor with HD-SDI input:
Figure 1: HD-SDI setup with Pomfort LiveGrade
The orange “Legal or Extended” labels indicate that cameras and monitors can be configured with
different settings for HD-SDI input/output:
Legal Range: Code values for luminance range from 64 to 960 in a 10bit (0…1023) signal. This is
the common setup and usually the default setting for HD-SDI signals.
Extended Range: Code values for luminance range from 0 to 1023 in a 10bit (0…1023) signal.
15
LiveGrade Pro Manual
HD-SDI Device Management
This is a special setting useful for certain workflows.
HD-SDI signal sources and destinations can usually be configure to output / expect legal or extended
range code values.
Figure 2: HD-SDI output configuration in the ARRI Alexa menu structure
Depending on these settings LiveGrade has to be configured accordingly to handle incoming and outgoing
signals. You can set the Legal / Extended range settings for each attached device in the Device Manager
screen.
Figure 3: HD-SDI setup in LiveGrade’s device manager
If the code value ranges of signal source (e.g. camera) and signal destination (e.g. HD-SDI monitor) don’t
match, you can even use Pomfort LiveGrade to convert one code value range into another. For example to
convert an Extended range signal coming from a camera to a Legal range signal for a HD-SDI monitor, set
the HD-SDI settings as follows:
Figure 4: Converting code value ranges from Extended to Legal

LiveGrade Pro Manual
HD-SDI Device Management
Important Note:
To see the color transformations made by LiveGrade on SDI-Out, please make sure, that the “Send to all
video outputs” checkbox is set in the BlackMagic HDLink Utility (the software comes with the
devices). Without this checkbox checked HDLink will only display modified colors on the DisplayPort,
DVI, and HDMI ports.
Figure 5: Setting up the SDI-Out of HDLink for color transformations from LiveGrade
For more information about compatible HDLink devices, see Supported HDLink models.
DVI, HDMI and DisplayPort setup for LiveGrade
To properly setup your viewing environment with a monitor connected via DVI, HDMI or
DisplayPort there are some things to consider depending on your setup. The following figure shows an
example of a setup with a HD-SDI signal coming from a camera going to a monitor with DisplayPort
input:
Figure 1: DisplayPort setup with Pomfort LiveGrade
17
LiveGrade Pro Manual
HD-SDI Device Management
The orange “Legal or Extended” labels indicates that cameras can be configured with different settings for
HD-SDI output:
Legal Range: Code values for luminance range from 64 to 960 in a 10bit (0…1023) signal. This is
the common setup and usually the default setting for HD-SDI signals.
Extended Range: Code values for luminance range from 0 to 1023 in a 10bit (0…1023) signal.
This is a special setting useful for certain workflows.
HD-SDI signal sources and destinations can usually be configured to output legal or extended range code
values.
Figure 2: HD-SDI output configuration in the ARRI Alexa menu structure
The orange “ICC Profile” label in Figure 1 indicates that regular computer monitors with DVI, HDMI or
DisplayPort inputs usually don’t have standardized calibration profiles (in contrary to most monitors with
SDI-IN which conform to the Rec.709 profile). With LiveGrade the color processing in the LUT box can
be adapted to an available ICC profile for the used monitor.
You can set the Legal / Extended range settings for input as well as the output ICC profile for each
attached LUT box in the Device Manager screen. For more information about using ICC profiles and color
management please see Color management with ICC profiles in LiveGrade.

Legal and Extended - SDI-Signals and LUTs in LiveGrade
HD-SDI signals
Devices supporting HD-SDI (YCbCr) signals can be configured to carry either legal range signals (which is
a standard use case for most of all HD-SDI signals) or extended range signals (which is only used in
special, rare use cases).
A 10-bit digital signal can theoretically carry code values from 0 to 1023. A legal range signal only uses
code values 64 to 940 (for the Y channel) while an extended range signal uses code values 4 to 1019 (for
the Y channel).
3D LUTs
3D LUTs are applied on RGB images. In post production systems, RGB images are usually using all the
code values available – so for example a 10-bit RGB image uses code values 0 to 1023. This means that
lookup tables made for post production systems expect that code values 0 to 1023 should be transformed
with that LUT.
Processing chain in LiveGrade
To be able to compute color manipulations in a defined code value range, LiveGrade converts incoming
signals so that code values 0 to 1023 are used (see Figure 1). So the processing chain of LiveGrade
simulates a post-production pipeline for color processing. This means that LiveGrade’s CDL mode
always will expect regular, “extended-range” lookup tables (3D LUTs).
Please note that the order of CDL and LUT can be changed. Please see KB 435 for more information about
the CDL grading mode.
21
LiveGrade Pro Manual
HD-SDI Device Management
Figure 1: Color processing in Livegrade
The HDLink device doesn’t know what kind of signal is coming in (legal or extended), so LiveGrade takes
care about this and converts the signals accordingly as part of the color processing – depending on what is
set in the device manager. So as long as you properly specify in the device manager which kind of signal
you’re feeding in, the look (e.g. CDL and and imported LUT) will always be applied correctly. See KB
238 and KB 216 for more information about the device manager.
Another example shows a situation, where the input signal is an extended range SDI signal, LiveGrade (as
always does the color manipulations in RGB (“full range”) and converts the signal in a way that the
HDLink device sends it out as a legal-range SDI signal (Figure 2).
Figure 2: Color processing with Extended-IN and Legal-OUT settings
NOTE: A situation where you would use a “legal range” 3D LUT is when you want to load it directly into
HDLink with the HDLink Utility application for use with legal SDI signals. Then the LUT will have to be
suited to the signals coming in. In LiveGrade only “full range” 3D LUTs are used, as in most post
production tools.
IS-mini licensing process

LiveGrade Pro Manual
HD-SDI Device Management
figure 1: IS-mini device
Since LiveGrade 1.4 has been introduced support for the Fujifilm IS-mini device, all the features
previously available in LiveGrade PRO are ready to work with this device.
The licensing process using an IS-mini device is slightly different. Now, in addition to the LiveGrade PRO
app license key, an IS-mini device license file is needed.
figure 2: IS-mini device licensing
The IS-mini device license file is provided by Fujifilm Corporation, but you can acquire it through
LiveGrade PRO. To start the process connect your IS-mini to the computer and open the Device Manager.
The IS-mini device should appear in one of the slots with an orange dot:
figure 3: unlicensed IS-mini
Click on the «Config…» button and then on «Buy Device License File for IS-mini…» as shown in figure 2
#1. This will redirect you to Fujifilm’s store to purchase the license for your device. You may need the
device identifier (figure 2 #4) in order to purchase the license file. Please be aware that the licensing
process can take from a few minutes to several hours due to time zone differences. Once you receive the
IS-mini device license file from Fujifilm, click on “Install License File” (figure 2 #2) and navigate to the
location of the file. Load it and LiveGrade will check it. If the License File is valid, the connection status
light should turn green with the message “Licensed”. The “Manage Installed devices” button (figure 2 #3)
will let you copy or delete the stored IS-mini device license files. The IS-mini device will be supported only
by the PRO version of LiveGrade.

Using automatic naming schemes when exporting grades
Different metadata information can be added to each grade through the Grade Library panel. Adding this
information can be helpful to identify your grades and to automatically match them to clips using
Assimilate Scratch.
When these grades have to be exported, LiveGrade offers the possibility to name them using a
combination of the metadata fields. This way, grades can be easily identified along the post workflow. The
naming schemes are also available when saving grades or exporting the LUT package.
In order to export a grade as a 3D LUT, go to File > Export selected Grades as 3D LUT.
31
LiveGrade Pro Manual

Here you can edit the naming scheme by replacing the original wildcards by the available ones. Simply
drag and drop them on the «Name» box to create the custom name. However, have in mind that
LiveGrade can only use information already added to the grades, otherwise a placeholder will be written
in its place. You can see if a grade has a certain information in the «Availability» column.
Note: wildcards are usually separated by an underscore sign «_». In addition, a forward slash «/» can be
used to create a folder structure. Here you can see an example:

CDL Server Workflow with Alexa XT & Others
Overview
Some onBoard Recorders such as the CODEX M, or cameras like the ARRI Alexa XT family with the
integrated XR module have an integrated CDL capture that stores ASC Color Decision List in metadata.
33
LiveGrade Pro Manual
Exporting grades and workflows
Figure 1: “Codex Workflow with LiveGrade PRO”
These devices can be connected via Ethernet to LiveGrade and then give you the ability to capture CDL
(color decision list) values at the time of recording. These settings then travel via metadata with the image
files and can then be applied to your deliverables via the Codex Virtual File System (VFS). The above
scheme shows a typical setup on set.
Setup a CDL Server
Using a CDL Server, LiveGrade can provide CDL values for a CODEX recorder. When configured, the
recorder will automatically use the CDL values to apply the grade to the recorded clips. You are able to set
up to three different servers simultaneously in each LiveGrade grading slot.
To connect a Codex Recorder with a CDL Server follow this steps:
Setting up LiveGrade
1. Start LiveGrade PRO.
2. Open the Device Manager and create a new grading slot:
figure 1: empty grading slot
3. Click on «Add Device…» and choose the «CDL Server» item (figure 2) to setup a CDL Server.
figure 2: adding a CDL server
4. Once the virtual device has been added, click on «Config…». Here you can define and enter your port if
you are considering to setup a different port than default value “6666″. The allowed port range is from
1024 till 65535. Alexa XT cameras only accept the default 6666 port.

into the Alexa or ACES grading modes.
figure 5: CDL mode locked
Configuring and connecting the CODEX recorder
Set Codex to receive CDL values
1. Connect your running LiveGrade PRO machine with the CODEX recorder via Ethernet. Make sure a
connection is established. You can use for e.g. the CODEX UI Tool
2. Telnet to your Codex recorder via the Terminal command line.
3. Insert the line “FilmlightCDLEnabled” in /etc/codex/sysconfig
On the Codex recorder
1. Set in the menu of your CODEX device the IP address and port 6666 from LiveGrade (e.g.
“192.168.2.218:6666″) as the CDL server address in the System menu.
2. You are ready to record a clip and the current grade of the configured slot in LiveGrade PRO is
written to the recorded clips.
Multiple CODEX CDL server
With LiveGrade you are able to set up to 3 different CDL servers using CODEX recorders. If you want to
have different CDL values for each recorder, please configure different ports in the Codex CDL Server
configuration, but please note that this can’t be done with the Alexa XT. The Alexa XT will always connect
at port 6666.

Setup the Alexa XT
Using a CDL Server which ships automatically with the Alexa XT while recording in ARRI Raw, LiveGrade
can provide CDL values for the camera. When configured, the recorder will automatically use the CDL
values to apply the grade to the recorded clips.
After setting up LiveGrade. to connect a Alexa XT in RAW Mode with a CDL Server follow this steps:
Configuring and connecting the ARRI Alexa XT
Set Alexa XT to receive CDL values
1. Switch the Alexa to record in ARRIRAW Mode, and make sure the Alexa XT is connected with the
Ethernet port and the same sub net mask of your computer with LiveGrade PRO.
2. You can check if the network connection between the computer with LiveGrade PRO and the Alexa
camera works by typing «ping [IP Address Of Alexa]» (for example: ping 169.254.2.10). If you get
replies, the connection works.
3. In the Alexa User menu press the Color Button of the User Interface and then as shown in figure 5
press the “Set Look” option
4. There you can set your IP address for the CDL Server (in that case the IP address of the computer
running LiveGrade PRO) like in figure 6

Error Handling
The most common issue connecting to your ARRI Alexa XT is a wrong network configuration. Make sure
you are using the same network range and set the same IP address of both Alexa XT and your mac
accordingly. You can use the Network Utility tool to figure out the IP address of the computer running
LiveGrade. You will be notified if you are using a port number that is not allowed.
Export LUTs for the AJA LUT-box
Due to the design of the AJA LUT-box LiveGrade is not able to use it for real time color grading. However
a 3D LUT can be created with LiveGrade and exported and uploaded onto the AJA LUT-box.
In order to be able to upload a LUT into the AJA LUT-box, you have to export it from LiveGrade into a
specific format. To do so select it form the Grade Library and go to File > Export selected Grade as 3D
LUT:
figure 1: exporting a 3D LUT
Then on LUT format, you have to select «AJA LUT Box» on the drop down menu:

Exporting grades to Scratch via ALE
LiveGrade offers the possibility to transfer CDL grades to Assimilate Scratch through an ALE file. This
feature will help you to match the grades with each clip automatically using their metadata information.
In addition, there is the advantage of having all the grades in one single ALE file. As long as camera and
scene information are entered for each grade in LiveGrade, the exported ALE file will transfer the
metadata along with the CDL values to automatically apply the grades to each clip in Scratch.
39
LiveGrade Pro Manual
Exporting grades and workflows
There are some considerations to have in mind when using this feature:
it only applies to grades created in the CDL or ACES grading mode
the 3D LUT information is not included (i.e. a LogC to Rec.709 LUT). Only the CDL information
and the LUT name is transferred. The same LUT has to be applied down the post workflow
camera and scene information has to be properly set on the grades
In order to start the ALE export, you have to select the Grade Group from the LiveGrade library. Then
select File>Export grade Group for Scratch (ALE) as shown in figure 1.
figure 1: exporting grade group as an ALE file
This will bring you to a save destination dialogue:

3.Applying a lookup table (3D LUT)
If you are using a 3D LUT in the LUT panel of the CDL grading mode in LiveGrade (for example as a
preview LUT for log-material), make sure that this LUT is also used in DaVinci Resolve.
Depending on the order of filter panels in LiveGrade you might configure Resolve for Loading a “3D Input
Lookup Table” or a “3D Output Lookup table” in the “Config” room.
If in LiveGrade the CDL controls are in the upper slot, the LUT is applied after the CDL values and
you need to set the LUT in Resolve as output LUT.
If in LiveGrade the CDL controls are in the lower slot, the LUT is applied before and you need to set
the LUT in Resolve as input LUT.
Learn more about LiveGrade’s CDL grading mode.
Alexa Look mode
Resolve doesn’t support the import of Alexa Look files (xml) directly, but you can instead export a 3D
LUT in LiveGrade and import that on a per-clip base into Resolve.

will be able to control LiveGrade PRO. For this reason, we recommend to set a password in the
Preferences panel.
The LiveGrade PRO iOS Remote is available from the App Store.
False Color mode in LiveGrade
LiveGrade has two False Color modes, which show areas of a certain brightness with different colors.
These modes are called «Ranges» and «Gradient». To switch between both False Color modes, users have
to modify LiveGrade’s preferences as shown in figure 1:
57
LiveGrade Pro Manual
Advanced features
Figure 1: False Color Mode preferences
With the Ranges mode, LiveGrade displays four different colors:
Blue: Colors near black clipping
Green: Colors around 18% medium grey
Pink: Colors around one stop over 18% medium grey (Caucasian skin)
Yellow: Colors near white clipping
All other areas are shown in black and white for better perception of the highlighted areas.
The Gradient mode shows a continuous range of video brightness levels from 0 to 100 IRE. The range
starts from blue for clipped shadows (0 IRE) to white for clipped highlights (100 IRE).
NOTE: These values are chosen to help determine the exposure of an ARRI Alexa Log-C image. For other
cameras with other response curves there might be deviations.
An example can be found in Figure 2:

Color management with ICC profiles in LiveGrade
For a color managed workflow for displaying digital images on a monitor, the color profiles of the source
image data as well as the display device must be known.
Source images
Images sent as SDI Signals usually conform to the Rec.709 color space. So for example the Alexa’s output
can be set to Rec.709 directly or the LiveGrade application converts the Log-C signal from an Alexa to a
Rec.709 signal.
60
LiveGrade Pro Manual
Advanced features
Display devices
Reference monitors with SDI inputs usually come with their own calibration tools so that they always
conform e.g. to Rec.709. When you use the HDLink devices to transform an SDI signal to HDMI,
DisplayPort or DVI, you will have a monitor attached, that is most probably not calibrated to the Rec.709
color space.
Color management
For computers color management takes care about the proper transform of image data so that it is
displayed properly on a certain device. So for example on Apple’s OSX the ColorSync system transforms
the image before it sent to the monitor in according to the monitors characteristics. This is done by using
ICC profiles to characterize image sources such as QuickTime clips as well as display devices such as
monitors.
LiveGrade
LiveGrade can use the ICC profiles available for a certain monitor to do the same color management.
For more information on how to set up the ICC profiles in the device manager see the
article http://kb.pomfort.com/?p=238. In figure 1 you can see the color pipeline for ARRI Alexa that
LiveGrade sets up to apply it to images going through a HDLink box:
Figure 1: Color pipeline for Alexa with LiveGrade
ICC profiles for your monitor
There are two possibilities for getting the right ICC profile for use in LiveGrade. Either the ICC profile
comes with the display or is downloaded from a database of such profiles
(e.g. http://www.tftcentral.co.uk/articles/icc_profiles.htm ), or you create it yourself by using a color
probe and a profiling software.
To give you an idea, here are the basic steps needed to create an ICC profile for example with the I1
Display Pro probe by X-Rite:
1. Attach the DVI/DisplayPort/HDMI monitor that you want to use with LiveGrade and HDLink later
to your computer.
2. Start the profiling application (e.g. the i1Profiler application that comes with the i1 Display Pro
probe).
3. Attach the color probe to your monitor. The probe is a small device that measures the colors
displayed by the display.
61
LiveGrade Pro Manual
Advanced features
4. Perform the profiling. The profiling application will display a bunch of colors on the monitor, the
probe will measure these colors and from this information an ICC profile is created.
5. Save the resulting ICC profile for the monitor.
6. Remove the monitor from your computer and attach it to the HDLink box.
7. In LiveGrades open the device manager and load the freshly created ICC profile for the attached
monitor / HDLink.
Note: If you experience bending artifacts in the image while using ICC profiles you can limit the use of
ICC profiles to display curves in the preferences. You can find more info and examples
here http://kb.pomfort.com/?p=303.
Conclusion
The resulting color reproduction will be much closer to what you would see on a reference monitor as
without the profile. Computer monitors come with all kinds of “wide gamut” and “super contrast” panels
that are far away from the way smaller color space and gamut of Rec.709. Your image will in almost any
case look way too saturated and crunchy without the ICC profile.
This can finally be corrected by using ICC profiles for HDMI/DisplayPort/DVI monitors with LiveGrade.
LiveGrade - Curve Editor
The curve editor allows you to precisely grade your footage.
To add a point just click on the curve, and in order to modify it’s value just drag and drop.
To remove a point simply move it out of the curve editor’s window.
When you move your mouse over the curve editor, the graph shows you the value of the exact point
where it is.
In LiveGrade you can find two types of curve editors:

LiveGrade's "Cube-o-Scope"
LiveGrade offers an unique visualization of the resulting lookup table (3D LUT) of all color
transformations. It assists in interactively manipulating colors of an SDI signal and visualizes the
changes in code values.
The Cube-o-Scope displays entries of a 3-dimensional lookup table in their source color and their
destination position.
So for example
if you change the highlight values to a more greenish color, you will see all corresponding color
values move to the green corner;
if you change the saturation, the color values will move the central, neutral position of the 3D cube.
The visualized 3D LUT includes all color transformations of the SDI signal such as:
Legal / extended range SDI settings (if applied),
ICC profiles (if applied), and
the color transformation of the current grading mode.

Cube-o-Scope has two display modes: It can display in an RGB cube (figure 1) and in an HSV cylinder
(figure 2). Use the selector buttons (yellow rectangle in figure 1+2) below the visualization to change the
display mode.
To inspect all aspects of the lookup table properly the visualization (cube or cylinder) can be rotated
around by click-dragging on the visualization.

Can I convert ASC-CDL, Alexa Looks, and LUTs
This article tries to clarify the conceptual differences between LUTs, ASC-CDL and Alexa Look files and
answers the question if and how these formats can be converted between each other.
Parameter files: ASC-CDL and Alexa Look files
ASC-CDL and Alexa Look files contain parameters color transformations specific to each format. Behind
both color transformations there stands a well defined mathematical formula.
Both ASC-CDL files and Alexa Look files store the parameters in a custom XML format.
ASC-CDL
For example the formula for CDL consists of some multiplication, addition and power functions and a
saturation function.
Figure 1: Formula for CDL
The notations is read as follows:
F is the name of the formula, with the followinng intput values:
t is the input RGB triple
o is the offset or “shadows” values for each color channel
p is the power or “midtones” values for each color channel
s is the slope or “highlights” values for each channel,
sat is the saturation value,
t’ is the output RGB triple, and
F Saturation is the formula for saturation.
Alexa Looks
The formula for Alexa Looks is a bit more complex, it consists of several functions such as matrix, a curve
and also similar elements as the CDL formula.
The formulas of ASC-CDL and Alexa Looks are different in a way that you can’t convert the parameters for
the ASC-CDL color transformation to Alexa Look values or vice versa.
Lookup tables: LUT files
A LUT file is a representation of a color transformation. Such a color transformation can be any
modification of colors. So a LUT can represent for example a simple color transformation such as an

Troubleshooting
overall slight rise in brightness as well as a much more complex transformation with a luma key that
desaturates the blacks.
To create a LUT the given color transformation is applied to a fixed (usually large) set of colors.
In the following example (figure 2) we apply a brightness transformation to a very small, fixed set of 27
colors.
Figure 2: Creation of a simple LUT from a brightness transformation
The left color patches are the fixed set of input values, the resulting LUT contains the color values of the
right color patches.
A typical LUT doesn’t contain just 27 values but usually tens of thousands of values to cover more
different colors.
To apply a LUT to an image, the color of each pixel gets looked up in the set of input colors (in the
example the patches on the left) and is replaced by the corresponding color of the LUT (in the example the
patches on the left). If a color can’t be found in the input colors, the resulting color has to be interpolated
between similar colors.
For LUT files several proprietary formats exist, but all consist on a huge set of numbers.
Transforming ASC-CDL and Alexa Look files into LUTs
Both ASC-CDL and Alexa Look files can be transformed in to LUT files. Figure 3 illustrates that with an
example 3x3x3 (27 element) LUT. A typical (33x33x33) LUT would contain much more (35.937)
elements.
Figure 3: Creating LUTs from example ASC CDL and Alexa Look
Transforming a LUT into Alexa Look or ASC-CDL values ?
The way back from a LUT file to Alexa Look or ASC-CDL values is generally not possible. As an example
figure 3 shows a LUT that leaves all colors the same – except that it replaces the green color by a medium
blue.
67
LiveGrade Pro Manual
Troubleshooting
Figure 4: There is no generic method for deriving a color transform and parameters from a LUT
This given example LUT can’t be represented by a ASC-CDL or a Alexa Look color transformation.
Even if a LUT might not include such “exotic” color transformations as in our example, you cannot find
parameters for the ASC-CDL or Alexa Look formulas that matches a given LUT. Depending on the
software and the color controls that created the given LUT, you can’t even get close.
The only exceptions are LUTs that already have been create from an Alexa Look or ASC-CDL – but even
then there is no common algorithm to get these parameters back.
Avoiding Bending Artifacts with ICC profiles in LiveGrade
For use in the HDLink box LiveGrade transforms ICC profiles into 3D LUTs together with all other look
processing. Due to the limited number of nodes in the HDLink’s 3D LUT support (17 x 17 x 17 nodes),
some ICC profiles may produce colored bending when used in LiveGrade.
Figure 1: Sample images of colored bending when using ICC profiles.
You can limit the use of ICC to display curves, which in most cases avoids bending artifacts. You can set
that in the Preferences dialog of LiveGrade:
Figure 2: Configuring ICC processing of LiveGrade

Troubleshooting
Switching this setting on has the cause that only the response- or gamma-curve of the ICC profile is
applied, but the matrix for the primary colors is skipped.
Troubleshooting connecting with Pluto

LiveGrade Pro Manual
Troubleshooting
LiveGrade is made to control multiple HDLink devices. With LiveGrade you can
switch between attached devices,
manage them in the device manager, and
control the selected one with the color controls independently.
If you read “No devices found, device simulation mode” below the “Manage Devices…” button, no
HDLink device could be found.
Press the Reload button besides the “Manage Devices…” button to search for devices.
If you still have troubles with controlling HDLink devices, please check the following things:
Restart (power-cycle) all devices
Make sure the latest firmware is installed on the HDLink devices.You can download and install
firmware on the HDLink devices through the HDLink Utility provided by Blackmagic
Design: http://www.blackmagic-design.com/support/
Can you control each of the devices alone (without the others attached via USB)?
You can check this either with LiveGrade or the HDLink utility from Blackmagic. Do this to rule out
the possibility of a broken USB cable etc.
Can you blink each of the devices from LiveGrade?
Open the device manager and press the “Blink” button for each of the attached devices. The monitor
should blink in a sequence of red, green, and blue. If yes, LiveGrade detected and properly controls
the device.
Is each of the devices connected to a label in the device manager?
Make sure each device is attached to a label with the green draggable lines and that you can select
each one of the devices in the device selector from the main window. To control each device
independently, you have to select it with the device/label buttons on the left of the color controls in
the main window before controlling it.
NOTE: If the LUT isn’t applied to SDI-out at all, you might have an old firmware installed on the
HDLink device. Some older firmware versions don’t allow LUTs on all outputs. Please make sure your
HDLink device is running the latest firmware.
For more information about the operation of HDLink devices please see the HDLink Manual at
blackmagic-design.com
There are rare occasions where the HDLink comes into a state where it’s recognized by LiveGrade as well
as by the HDLink Utility, but color changes in LiveGrade as well HDLink Utility have no effect on
the image. In this case it may help if you
create a random grade,
send that to the HDLink’s NVRAM by choosing “Store Grades in HDLink’s NVRAM…” from the
file menu, and
power-cycle the HDLink (remove power and all other cables for more than 10 seconds).
