You can use Facebook Lint tool to debug OG objects, here it is on one of your domain links:
Notice that you have a problem with the og:url that shows http://embedible.com/ although your OG object url is actually http://embedible.com/video/amQ1Njg4QGdtYWlsLmNvbTI5OA==
you can see it on the Redirect Path section of the lint debugger, the actual url that was scrapped is http://embedible.com/
On my website we render the same html template with different data based on the url. So I have 2 template engines one for real views on the client and one on the server that fill the meta tags
Bottom line: you must replace the meta tags on your Server.
