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.
