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:
Choose Window > Show A/V Controls.
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.”
