Candela supports a technology called oEmbed, which is how you should embed YouTube, Open Assessments, and Slideshares (among other things) in open courses. If you use <iframes>, Candela will automatically delete what you embed in open courses.

YouTube

To embed a YouTube video, go to video’s YouTube page. Look for the “Share” button under the video, and copy the URL in the Share bar. Paste it into Candela.

The code will look like this:

and the end result will look like this:

Note: If a YouTube user has prevented the embedding of a video on a web page, the video frame will not appear in Candela. Instead, only the link will be visible. Here’s where you can check if a user has prevented embedding of his/her video content:
