Your works in progress in Movie Maker are stored in projects. A project (.mswmm) file isn't an end-result movie but a framework containing the arrangement and timing information of audio and video clips, video transitions, video effects, and titles that you've added to the storyboard/timeline. Project files also have properties that you can define and use to organize your projects.You open and save existing projects with the usual Open, Save, and Save As commands in the toolbar or File menu.To create a new project: Choose File > New Project. TipsYou can have only one project open at a time.Project files are saved by default in the My Videos folder inside your My Documents folder (choose View > My Videos Folder).Like most Microsoft applications, Movie Maker opens by default with a blank, untitled project. If you'd rather start editing where you left off, choose Tools > Options > General tab; then check Open Last Project on Startup.To view a project's properties: Choose File > Properties (Figure 11.7 ).
Figure 11.7. You can specify values for different properties (except Duration, which is preset) and use Windows Explorer to search for specific projects or organize them according to title, author, and so on.
TipsThe properties that you enter become part of the project file and of your final, saved movie. Don't enter any information in the Project Properties dialog box that you don't want others to see.To view an individual clip's properties (such as duration and source file), right-click the clip; then choose Properties.
