Fake email allegedly from Facebook?

Earlier this evening I downloaded an app from the App Store which enables you to add photos of friends onto cartoons where they dance and is quite hilarious. I uploaded three dance clips this way and fairly soon afterwards got an email purportedly from Facebook accusing me of infringing copywrite and threatening to close my Facebook account if I did not behave. I'm totally puzzled by this as some of the photos were taken by me myself and others by friends of friends of whom I know them all. I certainly did not upload any film clips nor any audio (as I am profoundly Deaf as are most of my friends).

This has got me a little bit worried. Does anybody here think this is a scam email especially as the email said my said clip had been taken down when it has'nt?
