Hap Video Codec (Andrea Terrasa)

The Hap video codec decompresses images on a computer's video card. It reduces the CPU usage needed to play back a movie. This is useful when the CPU is not powerful enough to work effectively with high resolution movies. This video codec only works for Mac OS X users.

Hap makes it possible to reduce the overhead of the playback. Hap, however, needs a host application such as VDMX to display its advantages. These advantages include the low usage of CPU despite the use of high resolutions. In addition, hap provides sufficient support for an optional alpha channel. It also creates reduced data through-put to graphics hardware.
