Video Components
#################################
You can add video components to any container in your course (such as
a vertical or sequential). Studio places all video components inside
verticals (which it calls units).
See:
* `Create the XML File for a Video Component`_
* `Video Component XML File Elements`_
* `video Element Attributes`_
* `Example Video Component XML File`_
**********************************************
Create the XML File for a Video Component
**********************************************
To add a video component to your course, add it to the course XML tree as:
.. code-block:: xml
<video
youtube="1.00:o2pLltkrhGM"
url_name="Introduction_Lecture"
display_name="Introduction Lecture"
youtube_id_1_0="o2pLltkrhGM"
</video>
If you would prefer to break this out into its own file, you create an
XML file in the ``video`` directory for each video component in your
course.
The name of the XML file must match the value of the @url_name attribute of the
``video`` element in the vertical XML file.
For example, if the vertical XML file contains:
.. code-block:: xml
<vertical display_name="Lesson_1_Unit_1">
<video url_name="Introduction_Lecture"/>
. . .
</vertical>
You create the file ``video/Introduction_Lecture.xml`` to define the video
component.
*************************************
Video Component XML File Elements
*************************************
The root element of the XML file for the HTML component is file is ``video``.
The ``video`` element contains a single ``source`` element.
==============================
``source`` Element
==============================
The ``source`` element contains one attribute:
.. list-table::
:widths: 10 70
:header-rows: 1
* - Attribute
- Meaning
* - ``src``
- The file path for the video file.
*************************************
``video`` Element Attributes
*************************************
.. list-table::
:widths: 10 70
:header-rows: 1
* - Attribute
- Meaning
* - ``display_name``
- The value that is displayed to students as the name of the video

Example Video Component XML File
*************************************
The following example shows an XML file for a discussion component:
.. code-block:: xml
<video
youtube="0.75:xGKlr7nT_Zw,1.00:o2pLltkrhGM,1.25:XGsB9bA6rGU,1.50:_HuIF16HdTA"
url_name="Introduction_Lecture"
display_name="Introduction Lecture"
download_video="true"
html5_sources="[&quot;https://s3.amazonaws.com/edx-course-videos/school/DemoCourseIntroductionVideo.mov&quot;]"
source=""
youtube_id_0_75="xGKlr7nT_Zw"
youtube_id_1_0="o2pLltkrhGM"
youtube_id_1_25="XGsB9bA6rGU"
youtube_id_1_5="_HuIF16HdTA">
<source src="https://s3.amazonaws.com/edx-course-videos/mit-6002x/6002-Tutorial-00010_100.mov"/>
