User Guide
Setting preview options
After Effects provides four options for previewing your animations: RAM preview,
standard preview, manual preview, and wireframe preview. You can access RAM,
standard, and manual previews using the Time Controls palette. Access wireframe preview
from the Composition > Preview menu.
A. First Frame B. Frame Reverse C. Play
D. Frame Advance E. Last Frame F. Audio
G. Loop H. RAM Preview I. Jog control
J. Time indicator K. Shuttle control
The preview options represent different balances between preview quality and speed:
RAM preview This option plays a preview of the frames (including audio) at the frame
rate of your composition or as fast as your system allows. Use RAM preview to preview the
footage in the Timeline, Layer, or Footage windows.The number of frames previewed
depends on the amount of available contiguous RAM allocated to the application. After
Effects displays the total number of frames requested for the preview and the number it
can render.
You have two choices of RAM preview settings: RAM Preview and Shift+RAM Preview.
Each provides different options. In the Timeline, RAM preview previews only the span of
time you specify as the work area. In the Layer and Footage windows, RAM preview
previews only untrimmed footage. Before you preview the Timeline, check which frames
are designated as the work area. See “Setting up a work area on page 121. Before you
preview the Layer or Footage windows, check to see that footage you may want to preview
has not been trimmed.
