NOTE
Using QuickTime Playback
The RADEON™ 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™ MAC® EDITION’s hardware scaler maintains the original quality of your QuickTime movie when scaling to a larger size – even full screen.
The RADEON™ MAC® EDITION’s QuickTime playback acceleration displays in millions of colors, even if the current color depth setting is 256 colors. When the monitor is set to display in grayscale, QuickTime movies are accelerated in grayscale, they are not converted to color. When scaling video,
RADEON™ MAC® EDITION uses special hardware techniques (alpha blending and chroma interpolation) to enhance the video quality instead of just repeating pixels.
To use RADEON™ MAC® EDITION’s playback acceleration, you must have QuickTime version 4.0 or greater installed on your computer.
Optimizing Video Playback
When you scale a movie, your computer switches from
QuickTime’s software scaler to RADEON™ MAC® EDITION’s hardware scaler to produce better results. However, QuickTime will not switch to hardware scaling in the following situations:
•playing video in double size
Try manually scaling the video slightly off exactly double the size.
•pausing the video
•using single frame advance
•watching the video in reverse
•playing a video that has not been saved in Cinepak, Indeo, or
