I have made a 10 minute movie with approximately 8 clips all shot with the same video camera. When I save the movie a hand full of videos pixelate. I have saved many time using different formats with the same results. I uninstalled and reinstalled movie maker (Windows essentials) with no improvement. I have made similar movies within the month without this problem. The version that I reins t called is build 16.3508..0205. Help!
