I recently used Movie Maker to edit a video taken on an iPhone that was upside down. I was able to flip the picture so it was right side up, but when I went to save the project in a format such as MP4 and WMV, there is no picture and only the audio.  I believe I'm running on Windows 8 (the Windows 10 upgrade did not go well)  Please help!
