The Home screen shows links to online training videos when you first start using Premiere Pro.If you have opened projects previously, a list will appear in the middle of the Home screen. You
can hover the pointer over a recent item to see the project file location in a pop-up window. As
your list of recent projects gets longer, the links to online training videos are removed to make
room for the list.
A Premiere Pro project file contains all your creative decisions for a project, links (referred to as
clips) to your selected media files, sequences made by combining those clips, special effects
settings, and more. Premiere Pro project files have the extension .prproj.
