A project holds information about the arrangement and timing of the items that appear on the storyboard/timeline, which include audio and video clips, video transitions, video effects, and titles. It does not contain the actual audio, video, and picture source files, but rather references them as clips. You can edit clips in a project without changing the source files. Once you're satisfied with the sequence of clips, videos, and pictures on the storyboard or timeline of your project, you can publish the results and create a movie.
The following table explains the differences between a project and a movie.
