Getting to Know Motion
When a section of your project is currently stored in RAM, the Timeline and the mini-
Timeline turn green to indicate which frames are stored.
RAM Previewing Regions
Previewing large sections of your project using RAM Preview requires large quantities
of RAM to store the frames. You may not have enough RAM to store all of the frames
you want to preview. You can restrict which frames are rendered either by choosing to
preview the play range or a selection. Using RAM Preview on a selection renders all
visible layers in the project from the first frame of the selection until the last.
To RAM Preview the play range:
