RT Extreme is the real-time effects architecture that allows you to play back multiple video
layers, video and audio filters, motion effects, and other effects in real time without
needing to render them first.

Introduction to Real-Time Processing

Final Cut Pro handles real-time processing with a feature called RT Extreme. The term real
time refers to an editing system’s ability to calculate the final image while maintaining
an acceptable frame rate and visual quality. In other words, you can see the results of an
effect as soon as you play your video. Real-time processing is the opposite of rendering,
in which you have to wait for an effect to be calculated and stored on disk before you
can see the results.

For basic editing tasks, Final Cut Pro handles real-time processing automatically, keeping
you focused on the creative choices at hand. However, if you work with a lot of effects
or if you color correct video footage, you should take some time to learn the details about
the real-time architecture of Final Cut Pro.
