Use Case: One Input Format Converted to One Different Output Format

This example shows how to implement the second use case from the typical scenarios. The input includes two captions languages, and the single output will convert those captions. For example, the input has embedded captions in German and French. You want to produce a UDP output with both captions converted to DVB-Sub, plus one video and one audio.

To set up for this use case

  1. In the channel that you are creating, in the navigation pane, , in Input attachments, choose the input. .

  2. For General input settings, choose Add captions selector twice, to create Captions selector 1 (for German) and Captions selector 2 (for French). In both cases, set Selector settings to Embedded source.

  3. Create a UDP output group.

  4. Create one output and set up the video and audio.

  5. In this output, choose Add captions to create a captions encode.

    • Captions selector name: Captions selector 1.

    • Captions settings: DVB-Sub.

    • Language code and Language description: German.

    • Other fields: Keep the defaults or complete as desired.

  6. Choose Add captions again to create another captions encode. Set up this encode for the French captions. Make sure that you set up the font fields for German and French in exactly the same way.

  7. Finish setting up the channel and save it.
