The subtitling tool allows you to add and edit subtitles directly in the timeline on a special subtitle track or by using the :ref:`subtitle-window`. You can also import (**ASS**/**SRT**/**VTT**/**SBV**) and export (**ASS**/**SRT**) subtitles.
.. .. versionadded:: 24.02

.. tip::
Kdenlive stores subtitles as .ass files, which means you might be interested in exploring some advanced ASS features. For more details, check out the `ASS File Format Guide <https://github.com/libass/libass/wiki/ASS-File-Format-Guide>`_ and `Aegisub's Documentation <https://aegisub.org/docs/latest/>`_.

This makes it easier to split up subtitles, where you have a transcription with one subtitle per line. This comes from a couple of situations:
1. You have put the audio through an external transcription service
2. You are adding subtitles to a song that you have the lyrics for
Resize
~~~~~~
Grab the end of a subtitle with the mouse and lengthen or shorten it as needed.
Set subtitle in/out can be achieved with the same shortcut as to set clip in/out (left/right parenthesis shortcut).

:alt: subtitle style
Creating, duplicating, deleting, and editing subtitle styles can be managed through the :ref:`subtitle-manager`.

Additionally, you can edit the assigned style directly using the edit button in the :ref:`subtitle-window`.
Create a style
~~~~~~~~~~~~~~
Subtitle styles can be created either within each subtitle file or globally.
1. Choose a subtitle file or the global space from the sidebar as the location for the new style.
2. Click :guilabel:`+ Add Style` in the :ref:`subtitle-manager`.
3. Enter the properties in the :ref:`subtitle-style-editor`.

:alt: subtitle move copy

.. note::
You cannot move or delete the style **Default**.
Assign a style to a subtitle
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can assign a style to the subtitle you are currently editing using the :guilabel:`Style` combobox in the :ref:`subtitle-window`. This style will be applied to **the entire subtitle**.

Kdenlive supports using ASS override tags to style **specific parts of the subtitle text**.
.. figure:: /images/effects_and_compositions/subtitle-window_page1.png
:scale: 60%
:alt: subtitle override tags
* A **highlighter** renders different parts of the tags in distinct styles, making them more distinguishable.
* An **auto-completer** automatically lists all valid presets as you start typing a tag name.
* The buttons above the text editor will automatically add or edit tags when pressed.
- Tags like "Set Position," which affect the entire subtitle text, will be added **at the beginning of the subtitle text**.
- Tags like "Toggle Bold," which affect only the text following them, will either be added **at the current cursor position** or **wrap the selected text in tags** if there is a selection.
* Additionally, you can use '\\r<style>' to reset the style of the subtitle after the tag.
.. _subtitle-multi-layer_subtitling:
Multi-layer Subtitling
----------------------
Kdenlive supports multiple subtitle layers. You can create, duplicate, and delete subtitle layers using the :guilabel:`Layer` tab in :ref:`subtitle-manager`.
.. figure:: /images/effects_and_compositions/subtitle-manager_event.png
:alt: subtitle event
A new subtitle layer can also be created by dragging an existing subtitle down beyond the bottom of the subtitle track or by adjusting the layer indicator in the :ref:`subtitle-window`.
.. figure:: /images/effects_and_compositions/subtitle-add_new_layer_on_timeline.gif
:alt: subtitle add new layer on timeline
Subtitles with a lower Layer value are placed behind those with a higher value.
Set the layer of a subtitle
~~~~~~~~~~~~~~~~~~~~~~~~~~~
When you create a new subtitle by double-clicking on the timeline, the subtitle will be placed on the layer under your cursor.
You can change a subtitle's layer value using the :guilabel:`Layer` indicator in the :ref:`subtitle-window`, or you can simply drag and drop the subtitle from one layer to another on the timeline.
.. figure:: /images/effects_and_compositions/subtitle-move_subtitles_between_layers.gif
:alt: subtitle move subtitles between layers
If you set the layer value higher than the current maximum, Kdenlive will automatically add a new layer.
Copy/Move layer between files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You can copy and move layers between different subtitle files using the :ref:`subtitle-manager`.
In the :guilabel:`Layer` tab, Simply drag a layer to the desired file in the sidebar. All events within the layer will be copied or moved to the new location.
.. figure:: /images/effects_and_compositions/subtitle-move_layer.gif
:alt: subtitle move layer
Default style of layer
~~~~~~~~~~~~~~~~~~~~~~
You can assign each subtitle layer a default style. Any new subtitles created on that layer will automatically be assigned this style.
To set this, go to the :guilabel:`Layer` tab in the :ref:`subtitle-manager`. Click the :guilabel:`Style` column of a layer item and select the desired style from the pop-up menu.
This feature is particularly useful when working with multiple speakers in a subtitle file, as it allows each speaker to have a distinct style effortlessly.

Due to the complexities of ASS tag rules, style editing in the Simple Editor can sometimes behave unpredictably. So it's best suited for simpler use cases before or after editing styles.
