Action Movie FX app for my iPHONE 4s

I'm using an app on my iPhone 4s called "Action Movie FX," and I want to import the video files to my MacBook Pro to edit them use them in iMovie. When I email myself the video from the app, my computer says it's a .MOV file, but Quicktime doesn't recognize it and can't play it. Anyone know how I can fix that?
