Edit the page onto which you want to insert the video. If you are using the Block Editor, paste the oEmbed URL for the video right into the content area, and it will automatically transform into a preview player for your video.
If you are using the Classic Editor, paste the oEmbed link right into the content area, on its own line. That link should automatically transform into a preview of your video.
You can find the oEmbed link by viewing the Media Central video in a new tab in your browser, clicking the "Share" button beneath the video, and then clicking the "oEmbed" tab.
To add the video, you can also click the "Add Media" button in the WYSIWYG toolbar.
On the left sidebar of the dialog, click the "Insert from URL" link, then paste in the oEmbed link for your Media Central video.
After you paste in the link, a preview of the video should load. Click the "insert into page" button on the bottom right.
