Setting project properties
Project Properties serve as your template for previewing your movie projects. The project settings in the Project Properties dialog box determine the appearance and quality of a project when it is previewed on-screen. To customize project settings, select File: Project Properties.
When customizing project settings, it is recommended that you make the settings the same as the attributes of the video footage that will be captured to avoid distorting the video images and have smooth playback without jumping frames.
When you customize project properties to be the same as the desired output settings for your project (for instance, setting project properties to DVD settings if you will output the project to a DVD disc), you can have more accurate previews of your final movie.
