Setup with sidecar captions

This example shows an ABR workflow where the captions are in sidecars. For example, you want to produce a Microsoft Smooth output with three video encodes (one for low-resolution video, one for medium, one for high) and one audio. These encodes are in a Microsoft Smooth output. You want to ingest embedded captions (in English and Spanish) and convert them to TTML captions, one for English and one for Spanish.

To set up for this use case, follow this procedure.

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

2. For General input settings, choose Add captions selector twice to create the following captions selectors:

   • Captions selector 1: for Embedded English.

   • Captions Selector 2: for Embedded Spanish.

3. Create a Microsoft Smooth output group.

4. Create one output that contains one video encode and set it up for low-resolution video.

5. Create a second output that contains one video encode and set it up for medium-resolution video.

6. Create a third output that contains one video encode and set it up for high-resolution video.

7. Create a fourth output that contains one audio encode and no video encode.

8. Create a fifth output that contains one captions encode and no video or audio encodes, and with the following settings for the captions encode:

   • Captions selector name: Captions selector 1.

   • Captions settings: TTML.

   • Language code and Language description: English.

9. Create a sixth output that contains one captions encode and no video or audio encodes, and with the following settings for the captions encode:

   • Captions selector name: Captions selector 2.

   • Captions settings: TTML.

   • Language code and Language description: Spanish.

10. Finish setting up the channel and save it.
