I am using Movie Maker 2012 on Windows 10.  After much compatibility wizard tinkering, I can get my file open and can get it to play.  When I play it through the movie maker software everything is fine.  However....when I save it as a movie file (mp4 or any other type) it rotates SOME of my video clips 90 degrees.  It is so frustrating because everything looks normal in the software, but then when I save it as a move and watch it, it is only some of the clips that are rotated incorrectly.  Any ideas or suggestions???  Thank you!!
