README - Greyscale Filter Effect

This sample code package shows how to define a custom effect for QuickTime 3 or later.

This effect uses a single source as input, and renders that source in greyscale. It also

allows for a brightness value which can range from -100...0...100. A value of 0 signifies

no change in brightness.

This is a very basic sample and a good place to start if you've never looked at

QuickTime effect code before.

This sample makes use of some code from the Dimmer2 Effect Framework. While Dimmer2 is

a recommended companion to this sample, it is more complex, using multiple sources,

multiple pixel formats, non-Macintosh support, tweens etc.

For developers who have asked for a quick and dirty single source filter sample, this one's

for you...

Enjoy,

QuickTime Team
