Adding Video
YouTube, Vimeo, and other video services
While editing a Post/Page, simply paste in the address (URL) for the video (just like if you were sending it to a friend). Do not use the embed code provided by the video service and do not make the URL a link or format it in any way (such as making it bold).
Just insert the URL to the video in the body of your post/page, e.g., http://www.youtube.com/watch?v=qCHk74nGHqQ
WordPress will take care of the rest, automatically embedding the video for you:
For videos hosted on our servers
While editing a post/page:
Click on the Movie icon in your toolbar — this will place the short code for video in your content’s body (the shortcode will be inserted wherever you placed your cursor)- Place the address (URL) to the video in between the two pieces of video code on your page.
For example: [video]http://media.news.health.ufl.edu/video/041611FinalGrad.m4v[/video]
