Changing Playback Preferences

You can change playback preferences by choosing QuickTime Player > Preferences. The available options include:

• Open movies in new players: Select to open movies in a new player window; deselect to replace the movie in the current player window with the new movie.
• Automatically play movies when opened: Select to make all movies start playing when they're opened; deselect to have the movie start when you click the Play button.
• Use high-quality video settings when available: When this option is selected, video looks sharper and smoother, but more processor capacity is used.
• Play sound in frontmost player only: Select to play the audio for only one QuickTime Player window (the active window); deselect to play the sound of all playing movies simultaneously.
• Play sound when application is in background: Select to play audio even if QuickTime is not the frontmost application; deselect to mute the audio when QuickTime is not the active application.
• Show equalizer: Select or deselect to show or hide the equalizer (which shows the presence of audio) in the QuickTime Player window.
• Show Content Guide automatically: Select to see the latest content listings when QuickTime Player first opens (unless you open a specific movie file).
• Pause movie before switching users: Select to automatically pause a movie when you use fast user switching to let another person use your computer.
• Hide selection indicators for empty selection. Select to have the selection indicators in the timeline removed when no frames are selected.
