Setting up Teradek COLR

Livegrade comes with support for Teradek COLR. The Teradek COLR is a LUT-Box that can be controlled hard-wired and wirelessly by Livegrade and offers a LUT size of 33 x 33 x 33.

Adding Teradek COLR as a grading device#

To exchange look information with Livegrade, the Teradek COLR needs to have a working network or USB connection with the Mac where Livegrade is running.

It’s also possible to wirelessly connect Livegrade to the Teradek COLR by choosing the wireless network the COLR device is producing from the list of networks on your computer.

Once a connection is established, you can add the Teradek COLR to any input slot using the slot manager.

Open the slot manager

• by clicking on the Slot Manager symbol in the toolbar or
• via the menu: Livegrade > [Slot Manager…]

In the slot manager, click on the input you want to add the device to.

Within an input click on + Add Device in the Grading Devices section and select Teradek COLR to add the LUT box to the slot.

After adding the Teradek COLR a configuration form will appear.

Configure and connect Teradek COLR#

• Host: enter the device’s IP address
• Look Update: Choose how to update the look on the device.
  • Interactive
    • Adjustments of the look will be sent immediately to the device.
  • Manual Upload
    • Adjustments of the look will be sent on “Upload Look” actions. These actions are available as menu items (Slots > [Upload Look to Device(s)] menu), Toolbar button, Stream Deck and Tangent action
• Channel 1: some Teradek COLR devices support multiple channels. When using such a device, you can activate or deactivate each channel for the current slot.
  • Pipeline: for each channel, the pipeline can be chosen to be HDR or SDR. Depending on that either the HDR or SDR pipeline will be sent to the channel of the LUT box
    • Note: this option is only available if “Use 2nd Pipeline” is activated in Livegrade’s grading settings.

Finally, click on Connect to add the device to the slot. After that the current look of the corresponding input slot will always be sent to the grading device as long as the input slot is in Live mode.

In order to change the configuration of the device

• disconnect the device via pressing the Disconnect button
• change the configuration and
• press Connect to connect to the device again

Working with the Teradek COLR in Livegrade#

The Teradek COLR can be used with different grading modes such as e.g. “CDL and LUT”, “CDL Advanced” or “ACES CDL”. The interaction speed may vary in different modes: As the COLR device natively supports CDL plus LUT grading modes, a setup with CDL plus LUT node in this order will interact fluently. Other more complex grading modes may interact a bit slower.

Above all, a look can also be applied to the HDMI output of the Teradek COLR. That even allows a conversion from HD-SDI to HDMI containing looks.
