Final Cut Pro debuts a powerful collection of new features for professional editors. A strikingly low-profile interface maximizes work space on any display. The new Magnetic Timeline 2 advances even further beyond traditional, track-based editing with automatic color coding and flexible layouts based on roles. The latest Final Cut Pro release also takes full advantage of the new MacBook Pro with support for the Touch Bar and wide color workflows.
