Alright so I am using iMovie 7 (yes its an old version but it does the trick) and I am trying to delete a ton of old clips that are not favorites or in current projects. Now I am able to reject them all and get the red line at the top of all clips to show that they are rejected, however when I click "move rejected to trash", nothing happens.

What am I doing wrong? Is it the simple fact that there are just soooooo many clips? Im lost.

Thanks in advance to any responses!
