To preview a composition using RAM Preview

RAM Preview allocates enough RAM to play the preview (with audio) as fast as the system allows, up to the frame
rate of the composition. Use RAM Preview to play the footage in the Timeline, Layer, or Footage panel. The number
of frames played depends on the amount of RAM available to the application.
In the Timeline panel, RAM Preview plays either the span of time you specify as the work area or from the beginning
of the Timeline. In the Layer and Footage panels, RAM Preview plays only untrimmed footage. Before you preview,
check which frames are designated as the work area.
Do one of the following:
1
•
To preview footage in the Timeline panel, make sure that the Video switch is turned on for the layers you want to
preview, and set the work area to the time span you want to preview.
•
To preview footage in a Layer or Footage panel, make sure that the layers you want to preview have not been
trimmed.
