Article summary

In most use cases, the main output (target) is a CDN used for playback of online video streams, but in some use cases, SDI video out is the main target.
For SDI output, use the Blackmagic Decklink Target. The component is relatively straightforward to configure and use.
 Currently, there are two different alternatives when adding a new Blackmagic Decklink target.

  • Blackmagic Decklink Target v2 - Supports both Windows and Linux OS. Output channels are predefined as SDI 1 - 16.

  • Blackmagic Decklink Target v3 - Supports both Windows and Linux OS. Compared to the v2, the v3 is optimized and requires significantly less processing time. Output channels are predefined as SDI 1 - 16.

  • Blackmagic Decklink Target v4 - Supports both Windows and Linux OS (Recommended). Compared to the v2, the v4 is optimized and requires significantly less processing time. Output channels use the Label of the Decklink card specified in the “Blackmagic Desktop Video Setup”.

  • Autostart when the application starts - Check this option to enable target at application launch. For autostart of targets, the Autostart target options also must be activated on the application level (See the chapter Performance panel)

  • Output channel  - Select the output channel

  • Display mode - Select the display mode. This depends on the project framerate. If the project framerate is changed, the target needs to be deleted and added again to display the correct Display modes of the target.

  • Device name - Selected device name

  • Commands:

    • Start playback - Starts the target

    • Stop playback - Stops the target

    • Playback state - Current playback state

  • Performance and properties:

    • Video width - The width of output video

    • Video height - The height of output video

* Debug properties. Only visible if "Show debug properties" are enabled in Settings.

Important!

The display mode frame rate should be the same as your project framerate. Otherwise, there is a risk of audio not being in sync.
