Using QuickTime Playback

NOTE

Using QuickTime Playback

The RADEONMAC® EDITION’s QuickTime playback acceleration allows you to stretch even the smallest movies to full screen size without compromising frame rate or image

quality. RADEONMAC® EDITION’s hardware scaler maintains the original quality of your QuickTime movie when scaling to a larger size – even full screen.

The RADEONMAC® 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,

RADEONMAC® EDITION uses special hardware techniques (alpha blending and chroma interpolation) to enhance the video quality instead of just repeating pixels.

To use RADEONMAC® 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 RADEONMAC® 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 MPEG-1 compressed format
