exporting events

Hello,

I edited a lot with Imovie and imported all my clips to the Imovie library and forget to import them just on my mac. So all my clips are in the Imovie library but not in my finder. How can I export them to my finder? I know I can copy the library completely, but I want to work with final cut pro x so I need my clips. I have OS X Yosemite and Imovie 10.0.9.

MacBook Pro (13-inch Mid 2012), OS X Yosemite (10.10.5)
