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

This example shows how to implement the second use casefrom 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.


  1. In the channel that you are creating, in the navigation pane, choose Channel and input details.

  2. Choose Add caption selector twice, to create Caption selector 1 (for German) and Caption 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 caption to create a caption encode.

    • Caption selector name: Caption selector 1.

    • Caption settings: DVB-Sub.

    • Language code and Language description: German.

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

  6. Choose Add caption again to create another caption 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.
