Using QuickTime Playback
The RADEON 8500 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 8500 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 8500 MAC EDITION uses special
hardware techniques (bilinear filtering) to enhance the video
quality instead of just repeating pixels.
To use RADEON 8500 MAC EDITION’s playback acceleration,
you must have QuickTime version 5.0 or higher installed on
your computer.
