# Input settings—Video selector
<a name="input-video-selector"></a>

This section lets you identify the video to extract from the input, and lets you enable the optional color space feature. 

1. In **Video selector**, choose **Video selector**. More fields appear. 

1. Complete **Selector settings** as specified in the table after this procedure. 

   Keep in mind that there is no button to add more video selectors because you can extract only one video asset from the input.

1. For all input types, complete **Color space** and **Color space usage**, but only if you want to configure the handling of color space. For more information, see [Handling complex color space conversions](color-space.md).

**Determining whether you need to create a video selector**

When you planned the channel, you should have [identified the video](channel-map-output-source.md) that you need to extract from this input. 

You must now determine if you need to create a *video selector*, to identify the specific asset to extract from the input. Some input types require selectors, some input types don't require them.

The following table specifies whether you need to create a video selector.
