Cannot view video clips in All Events folder
I recently updated to Yosemite and to iMovie 10.0.8. In iMovie, under Libraries there are the following folders: Photos Library, All Events, All Projects, etc. When I click on All Events I see one image window with 364 Video Clips in it, 17.5 hours of total video. While I can scroll back and forth and see the different clips in this one image window I cannot do anything else. How do I actually view these clips or get access to them? I don't want to loose these video clips but I can't figure out how to access them. Thanks for any help.
MacBook Pro (13-inch Mid 2012), OS X Yosemite (10.10.3)
