Previewing from RAM

Your previews will render quicker if you use the Preview from RAM feature. When you render a preview with this option selected, Premiere stores and processes the selected frames in RAM, instead of writing them to the disk and reading them back. This feature processes video, audio, and effects. If the video and audio information does not all fit in RAM, Premiere displays the message "Previewing from disk" and plays or renders a normal preview file on the disk. If there is enough RAM, the message "Retrieving Source Frames" is displayed and the preview is rendered in RAM.

If the processing demands are too great for your system, some frames are dropped during the preview. Remedy this situation by reducing the frame rate and frame size in the Video Settings panel of the Project Settings dialog box. Keeping the frame size small should also minimize the reduction in frame rate during previewing with this feature.

To view existing preview files when Preview from RAM is selected, use standard playback from the Timeline window or the source view of the Monitor window.
