System Requirements

All systems are not created equal, and the more power you have in your hardware, the

more you can do in real time (that is, without rendering) in Motion.

Here’s a brief explanation of how Motion leverages your hardware. If you’re thinking of

upgrading your system to run Motion, it might help you to decide what configuration will

give you the best results.

The following sections are a little technical, so if you start to lose track, don’t panic. Just

remember: Faster equals better, more RAM equals better, and a more powerful graphics

card equals better.

System Memory

Motion uses system RAM to cache all the objects that make up your composite through-

out your preview range (see the Glossary if these terms are new to you).

Here’s an example. Let’s say you are combining three QuickTime movies in Motion to

create a final, single image: your composite. Imagine that you have a moving fractal back-

ground clip (Element 1), a rotating web (Element 2), and some random boxes (Element 3).
