Drupal 8 comes with a really easy way to embed videos.
Table of Contents
Embed a Video
Step 1: Create a piece of content
Click the top navigation button that says "Content", then click the blue "Add Content" button. This will take you to a page to choose which type of content you want to add. Choose "Basic Page" (although you can use this feature on Articles, Events, Personnel, or any other content type that has the WYSIWYG controls). See screenshot below.
Step 2: Embed Video
Once you are in the "edit" mode of an existing page, or in the "add" mode for a new page, click the "Embed Video" icon. See screenshot below:
Step 3: Insert Video Link
Once you click the "Embed" icon, you will see a popup with a "Video URL" field. Simply got to another browser and navigate to your video in Youtube or Vimeo (these are the only two services that work using this feature) and copy and paste the URL from the address bar to get your video link. Paste that link into the "Video URL" field. We recommend NOT checking the "Autoplay" box. Click "Save". Next click the blue "Save" button on the page you created.
Step 4: Enjoy your video
Now that you have saved the content you created, you can now see your video.
To manage any part of your web site, you will have to be logged into the Drupal CMS.
