I am using WIndows 10  Movie Maker 2012

Working on a project.  Importing short videos form I phone 6.  All MOV files.  Load and watch great in editing window of MM2012

When saving the project, whether as a Windows Media File, or as a MPG4 the videos are pixilated. Frozen.  You can hear the sound and the time bar continues to move the video along but the frozen picture jiggles and wiggles.  I have yet to try videos from my video camera on here.  I use this to edit then make my home family DVD's.

Curious if I am using a version not compatible and perhaps if there is a product better suited.
