Some tweaking of text is needed then...
Not really.
Facebook video's embed fine:
But the link you tried to embed was a Facebook "mobile" page URL with a video as part of the page, it wasn't a Facebook video URL.
To embed that video you first need to visit the non-mobile Facebook page for the Boroondara Police Service Area -
https://www.facebook.com/eyewatchboroondara/
Then scroll down the wall to find the video. Right-click the video. Select
Show video URL and copy the URL (https://www.facebook.com/eyewatchboroondara/videos/1216813574997170/). Head back to CC and click the media icon. Paste in the video URL ... and hey presto:
... or just link to the page if you're on a mobile device as it'll be much easier.
Cheers,
Shaun
