So I am running Final Cut Express. I just got the program and when I go to preview what is in my timeline all I see in the playback is an imagine that reads Unrendered. I thought at first it was some default image but it wasn't. I have tried changing a few simple settings and done all the tutorials on apple's site to see if I have missed something simple. I am very new to video editing and so I am kind of a noob. Any help or advice would be great.
