Clips do not load into iMovie Project Browser
I have imported a full feature Creative Commons movie into iMovie to edit for a short music video. It downloaded in MP4 format and originally loaded into the Project browser but would not let me split clips. I've tried converting it to .MOV in MPEG Streamclip and now the clips don’t even show up in the Project Browser. I see the clips in the Event Browser but they will not load into Project Browser. I've tried converting it to .MOV in Quicktime where I was able to split a clip. I then tried to import that whole movie file into iMovie but it won’t import. What am I doing wrong?
iMovie 10, OS X Mavericks (10.9.5)
