Configuring the DeckLink 8K Pro

To configure the Blackmagic Design DeckLink 8K Pro card to operate as four independent single-link input/output channels, follow the steps below using the Desktop Video Setup application:

• Open the Desktop Video Setup application.

• Select the first device in the list representing the DeckLink 8K Pro card.

• Navigate to: Connectors > Connector Mapping

• Under Connector, select "SDI 1 In or Out."

• This setting reconfigures all four SDI ports (SDI 1 through SDI 4) to function as four independent single-link SDI channels.

• Each port can now be used individually for either input or output.

• To restore the quad-link configuration, return to the same menu and change the setting back to "SDI 1 to 4 In or Out."

• This will re-enable the card's ability to function as a single quad-link SDI connection for high-resolution workflows, such as 8K capture or playback.

Important Note:

• If this configuration is not changed and the card remains in quad-link mode ("SDI 1 to 4 In or Out"), it may still appear to function correctly. However, in this state, the same output signal will be mirrored across both SDI ports.

• Always ensure the correct connector mapping is selected for your intended workflow.

Resolve Project Settings

1. Enable Dual SDI Outputs in DaVinci Resolve

• Go to Project Settings

• Navigate to Master Settings > Video Monitoring

• Under Video Format, enable: "Use dual outputs on SDI"

This setting enables Resolve to send separate output streams (typically HDR and SDR) over different SDI ports.

2. Enable Dolby Vision and Complete Analysis

• In Project Settings, go to: Color Management > Dolby Vision

• Enable the checkbox: "Enable Dolby Vision"

• Return to the Color workspace.

• Set the SDR target display output as required.

• Analyze the clip or entire timeline for Dolby Vision metadata:

• Right-click the clip or timeline > Analyze All (if not already analyzed)

After configuration and analysis are complete, SDR and HDR video outputs will be routed as follows:

• SDI Port 1 → HDR Output

• SDI Port 3 → SDR Output

These outputs are recognized and handled properly by Flex and Pivot.
