Input settings—Caption selectors

If you want to extract captions from the input or to specify an external file as the source of the captions, this section is required. You create one or more captions selectors to identify the captions to extract. Typically, you identify different languages in each selector, but you could also identify different captions formats.

For each captions item that you want to extract or include, choose the Add captions selector.

To identify the caption assets to extract

  1. Choose Add caption selector once for each captions asset that you want to extract from the input.

    If you are creating a channel with multiple inputs, then you must extract the same captions languages from every input. For example, you must extract English and Spanish captions from every input.

  2. In Caption selector name, enter a name that describes the captions that you are extracting.

    If you are creating a channel with multiple inputs, then you must assign the identical name to the selector in every input. For example, create a selector called captions-english in every input, and a selector called captions-spanish in every input.

  3. In Selector Settings, select the format of the captions asset to extract. Then complete the fields that apply to that format.
