'''Core Video''' is a new pipeline model for digital video in [[Mac OS X]]. Partitioning the processing into discrete steps makes it simpler for developers to access and manipulate individual frames without having to worry about translating between data types ([[QuickTime]], [[OpenGL]], and so on) or display synchronization issues. |

Core Video depends on accelerated video cards for the use of [[Quartz Compositor|Quartz Extreme]], whereas non-accelerated video cards cannot show smooth blends and pixel shading effects, and thus make use only of Quartz (not Extreme). |
