I have made a video with Movie Maker that consists of .mov video files and a m4a audio file. The preview footage is fine, but when I made the movie, the footage flickered like crazy between pieces of footage. It is very irritating and I have no clue what could be causing this jumpiness. You can see the video here: https://www.youtube.com/watch?v=d092PFWUyTY I don't know much about computer lingo.
