Creating New Video Effects

You should read this section if you want to write your own video effects. If you are only interested in building applications that use effects, you can skip this section.

QuickTime video effects are implemented as Component Manager components--the standard mechanism for extending QuickTime. To implement your own effect, you create a new effect component .

An effect component is a specialized type of image decompressor component. Chapter 4, "Image Compressor Components," describes building image decompressor components.

The following sections take you through the implementation of a sample effect component. The sample effect is built on a framework of code that you can reuse when you implement your own effect component.
