When you
            have created a new composition, you can import media and then add
            it to your composition and start working—see 
                     Importing Media. 
         
         To import media:
         
         
            - Select File > Import or press Ctrl + I( for Windows and Linux)
               or Cmd + I(for Mac OS). 
               The File Browser appears.
                
- Navigate to the location (on your machine
               or network) where your media is stored. The View button at the bottom
               of the File browser allows you to change the Details view to a Thumbnail
               display in the Contents area, which is on the right side of the
               browser.
            
- In the Contents area, select the media
               file(s) you want to import. To select multiple files, press Ctrl + click. 
            
- Click the Import button, or right-click
               one of the selected media files and select Import File(s).
               The media files are imported
                  into the composition using an Image Import tool.
