QuickTime 7 Player: About A/V Controls

Learn about A/V Controls in QuickTime 7 Player.

QuickTime 7 Player features A/V Controls that allow you to control aspects of the audio and video being played. From the Window menu, simply choose Show A/V Controls. With these controls, you can easily adjust the sound balance and volume, and make changes to the bass and treble response. Handy sliders let you set playback speed and shuttle backwards and forwards through video frames. On systems with a Core Image-capable video card, you can even adjust video Brightness, Color, Contrast, and Tint.

If you are using a system with a Core Image-capable video card on Mac OS X v.10.4 or later, the A/V Controls window will look like this:

If you are using a system without a Core Image-capable video card, or using Mac OS X v10.3, the A/V Controls window will look like this:
