Videos from other web sources can be embedded in any pages using the source editor, using the following code as an example:
<video type="youtube" id="cZ34QYhtBcY" width="Video width (in pixels)" desc="Video Description."/>
Can be from Youtube, Vimeo or others, substitute the video host
On YouTube, this is the string of letters and numbers at the end of the URL- https://www.youtube.com/watch?v=fjsBpUNhdmA
This is how wide the video should appear, in pixels. You should default to 400 pixels, as this provides a good compromise between showing the video as a source of information, while not intruding on text content on the page
This description adds a piece of text to describe the video below the thumbnail which the video is embedded in. This means readers know what to expect when viewing the video.
