Using QuickTime Playback
The RADEON 7000 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 7000 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 of colors,
the ATI card utilizes the 3D engine’s capabilities to scale and
accelerate playback. When you use 256 colors (or grays), there
are too few colors to convert and display the movie, so
QuickTime acceleration is not supported. When scaling video,
the RADEON 7000 MAC EDITION uses special hardware
techniques (bilinear filtering) to enhance the video quality
instead of just repeating pixels.
To use RADEON 7000 MAC EDITION’s playback acceleration,
you must have QuickTime version 5.0 or greater installed on
your computer.
