This will open Compressor, another one of the programs gracing the Final Cut Suite, and the movie file will be open in the program. What Compressor will then do is to change the file type, shrinking it by removing tiny pieces of the film at specified points. Here you select a file type for both the video and audio. It is best to select the MPEG-2 90 Minute selection for video, and the Dolby Digital for sound. Now Compressor will compress both parts of the video separately, giving you two separate files.
