Anyone can upload video clips to the Facebook site but unlike YouTube and other online video sharing sites, Facebook doesn’t (officially) provide an embed code for their videos. That’s a problem for two reasons.
#1. You found an interesting video on Facebook but how you do share it on a blog since there’s no code to embed that video into your site.
#2. You can watch video clips on Facebook only if you are logged into your Facebook account. How do you share videos with friends who aren’t on Facebook?

How to Add a Facebook Video to your Web Site

Here’s a simple trick that will let you embed any Facebook video into your web pages.

Every video uploaded on to Facebook has a unique ID that you can find in the browser’s address bar (look for the value of parameter "v").
Copy that number and replace it with xxx in the code below.
<object width="400" height="224" >
 <param name="allowfullscreen" value="true" />
 <param name="allowscriptaccess" value="always" />
 <param name="movie" value="http://www.facebook.com/v/xxx" />
 <embed src="http://www.facebook.com/v/xxx" type="application/x-shockwave-flash"
   allowscriptaccess="always" allowfullscreen="true" width="400" height="224">
 </embed>
</object>
Now you can put that code on any web pages and the Facebook video will play just like any other Flash video. For instance, here’s a video on Facebook scams that you can watch even outside Facebook. Unfortunately, since Facebook videos are embedded using Flash, you can’t enjoy them on an iPad.
