The Player lets you play or preview a composition, or preview media. There are three different versions of the Player:
Player view Lets you play compositions and view the changes you make to compositions as you work—see Player View Default Settings.
Mini-Player Lets you preview compositions located in the File view—see Using the Mini-Player.
Fullscreen Player Is useful when you want a more immersive environment. You can use it to play compositions, work on compositions, and preview
media—see Using the Fullscreen Player.
