Chapter 1 Using QuickTime Player 19
Adjusting Audio and Video Settings
For any QuickTime movie with an audio track, you can adjust the right/left balance, as
well as the volume, bass, and treble levels. For any movie, you can also set playback
options such as speed and playback rate (the jog shuttle).
To set audio and video controls:
1 Choose Window > Show A/V Controls.
2 Drag a slider to adjust the setting.
Other playback options (for playing several movies at once or for playing a movie while
using another application, for example) are available in QuickTime Player Preferences.
To open QuickTime Player Preferences (in Mac OS X), choose QuickTime Player >
Preferences. In Windows, choose Edit > Preferences > Player Preferences. For more
information, see “Changing Playback Preferences.”
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.
With QuickTime Pro, more options are available. For information about them, see
“Viewing Movies at Full Screen” on page 22 and “Setting Recording Options” on
