In this tutorial, we'll be looking at how we can render from a Quartz Composer composition with real audio input of a specific file, within Quartz Crystal, prior to exporting the respliced audio and rendered video within GarageBand. This is the second part of a three part series of tutorials. A link is provided here for you to view the actual video file rendered from Quartz Crystal, as the screen capture technology I've employed here has slightly degraded the resulting exported movie file which you see a short snippet of at the very end of this tutorial.

However the tutorial itself is good quality video and is useful to anyone wanting to find out how to render and export with fidelity, an audio reactive Quartz Composer composition from Quartz Crystal, that incorporates a specific audio track. In the third and final part of this mini series, I shall be looking at how we can export our composition as a standalone application from Quartz Builder.. Here however, we are looking at going from Quartz Composer to Quartz Crystal to GarageBand and finally to QuickTime Player.
