In the previous post it showed you how to add subtitles to a movie with Windows movie maker. Now this video will show you how to save that movie to your computer. It will end up as a .wmv file which will be more compatiable with other players, including Windows media player.
If you have added subtitles or any special effects it will all be saved as one movie. The title, your movie, transitions, and end titles will all become one.
