| `Other Subtitles`                                        | `other`                                                                                   | Collection of Movies/Shows that are less common Languages.                     |

## Config

The below YAML in your config.yml will create the collections:

```yaml
libraries:
  Movies:
    collection_files:
      - default: subtitle_language
  TV Shows:
    collection_files:
      - default: subtitle_language
```

## Template Variables

Template Variables can be used to manipulate the file in various ways to slightly change how it works without having to 
make your own local copy.

Note that the `template_variables:` section only needs to be used if you do want to actually change how the defaults 
work. Any value not specified will use its default value if it has one if not it's just ignored.

??? abstract "Variable Lists (click to expand)"

    * **File-Specific Template Variables** are variables available specifically for this Kometa Defaults file.

    * **Shared Template Variables** are additional variables shared across the Kometa Defaults.

    * **Shared Separator Variables** are additional variables available since this Default contains a 
    [Separator](../separators.md).

        1. Each default collection has a `key` that when calling to effect a specific collection you must replace 
        `<<key>>` with when calling.

    The below is an example config.yml extract with some Template Variables added in to change how the file works.

    ```yaml
    libraries:
      Movies:
        collection_files:
          - default: subtitle_language
            template_variables:
              use_other: false #(1)!
              use_separator: false #(2)!
              exclude:
                - fr  #(3)!
              sort_by: title.asc
    ```

    1.  Do not create an "Other Audio" collection
    2.  Do not create an "Audio Language Collections" separator
    3.  Exclude "French" from having an Audio Collection

## Default Values

These are lists provided for reference to show what values will be in use if you do no customization.  **These do not
