Allocating Memory For Graphics; When You'll Need To Render Your Effects - Matrox RTMac Installation And User Manual

Allocating memory for graphics

Graphics are stored in RAM memory. The number of graphics you can work with in real
time depends on the amount of RT Still Cache RAM you've allocated in your Final Cut Pro
preferences. Increasing the amount of RAM lets you work with more graphics in your
project.
