10.3. 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).

10.3.1. Create the XML File for a Video Component

To add a video component to your course, add it to the course XML tree as follows.

<video
  youtube="1.00:o2pLltkrhGM"
  url_name="Introduction_Lecture"
  display_name="Introduction Lecture"
  youtube_id_1_0="o2pLltkrhGM">
</video>

If you prefer to place the video component in 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, the vertical XML file uses the following format.

 <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.
