I have made a short 4 minute movie using clips from my iPhone 5. I edited the movie and added music and it will play fine in the preview mode. When i save the movie or try to upload it to any site (Facebook, YouTube) all im getting is a black screen with the music i added. I have tried multiple times to save it in different places, different types and all the other options. Once saved it will not playback in any player i have including Movie Maker.
