The Home screen is where you begin in Premiere Pro. Use the options on the left to start a new project or open an existing project. The right side of the Home screen provides access to in-application tutorials, and other tutorials and documentation available online.
The content on the Home screen evolves over time as you use Premiere Pro. As you work on more projects and get more experience, your recent projects are displayed on the Home screen and the number of tutorials displayed are reduced.
