How to Post Embedded Videos on Facebookby Nick Peers
You can share videos from video sharing websites, such as YouTube, NetFlix, Vimeo and DailyMotion, on your Facebook Timeline. However, the videos must be embeddable to appear in a player box on Facebook. If a video is not embeddable, it is displayed as a hyperlink, and Facebook users can't play it on Facebook. They can, however, click the link to open the website and play the video there. Note that some videos can breach Facebook's Terms of Service, so repeatedly posting offensive videos can get your account limited or banned.
Posting Embedded Videos
Facebook is able to pull the video from the page if it is embeddable and display it in your status update, so you just need the URL of the page that contains the video. To get the URL, open the Web page in your browser, select the address in the Address bar and press "Ctrl-C" to copy it to the clipboard. To post the video on your Facebook Timeline, create a new status update and press "Ctrl-V" to paste the URL from the clipboard into the update. Facebook displays the video below the update, along with its description. Delete the URL from the update and then type or paste the text of the status update. To change the thumbnail of the video, click the right or left arrow buttons. To prevent Facebook from displaying a thumbnail, check the "No Thumbnail" box. Post the status update on your Timeline by clicking "Post."
