# Determining the number of captions selectors needed
<a name="determine-number-embedded-caption-selectors"></a>

To determine the number of captions selectors you need to created in the event, follow these rules:
+ **Embedded Passthrough** – Create only one captions selector. With this scenario, all languages are automatically extracted and are automatically included in the output.
+ **Embedded In, Other Out** – If you are setting up embedded-to-other, create one captions selector for each language that you want to include in the output, to a maximum of four selectors.
+ **A combination of Embedded passthrough and Embedded conversion** – If you are setting up embedded passthrough in some outputs and embedded-to-other in other outputs, create one captions selector for each language that you want to include in the output, to a maximum of four selectors. Do not worry about a selector for the embedded passthrough output. Elemental Live will extract all the languages for that output, even though no selector exists to explicitly specify this action.
