# ClearView Dual Stream Guide

Setting up DaVinci Resolve for a simultaneous Flex and Pivot stream

## 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**.
