Step 2: Create captions selectors

After you have created a list of captions selectors, you can create the captions selectors in the event.

To create the captions selectors

  1. In the event, in the Input section, choose Advanced.

  2. Choose Add Caption Selector.

  3. For Source, choose the format of the source captions.

    To identify SMPTE-TT as the source captions, choose TTML. When Elemental Live ingests the captions, it automatically detects that they are SMPTE-TT.

  4. For most formats, more fields appear. For details about a field, choose the Info link next to the field. In addition, see extra information about DVB-Sub or SCTE-27, on Embedded, on SCC, on SMI, SRT, STL, TTML, on teletext, or on Null.

  5. Create more captions selector, as required.
