Facebook iMovie infringement

[WatchTower]

I've just uploaded a video of clips I put together of my holiday on Facebook and it's been taken down. Now all the video I recorded myself the only music I used and sound effects were from iLife. I thought I was free to publish videos using audio from iLife. Is it a mistake by Facebook or me?

I would have thought that by using the iMovie default sounds, and your own footage, you would be free to use them and "publish" them on FB.

When it was taken down, did it give a more detailed answer? i.e. when youtube videos are taken down they say because "X has complained of copyright infringement".
