NOTE Using QuickTime Playback The RADEON 9000 PRO MAC EDITION's QuickTime playback acceleration allows you to stretch even the smallest movies to full screen size without compromising frame rate or image quality. RADEON 9000 PRO MAC EDITION's hardware scaler maintains the original quality of your QuickTime movie when scaling to a larger size - even full screen. When the monitor is set to display in grayscale (Mac OS 9 only), QuickTime movies are not accelerated, nor are they converted to color. When playing movies in thousands or millions of colors, the ATI card utilizes the 3D engine's capabilities to scale and accelerate playback. When scaling video, the RADEON 9000 PRO MAC EDITION uses special hardware techniques (bilinear filtering) to enhance the video quality instead of just repeating pixels. To use RADEON 9000 PRO MAC EDITION's playback acceleration, you must have QuickTime version 5.0 or higher installed on your computer. 12
