It keeps Crashing! – iMovie Review

I was making a talking Tom video that is over 10 minutes but now it crashed. I Opened the App again but when I touched the play button, it crashed again! I opened it again and scrolled to the right and Crashed! But I opened it again and I pressed “Done” But It didn’t crash so I got back to edit and It turned out It was working but I scrolled further to the right but now It crashed. So you guys need to fix it!
