Play RAM preview at the full size of the composition, layer, or footage item on a screen that is the panel background color. You
can change the panel background color using the Brightness control in the Appearance preferences.
2. Do one of the following:
To preview using RAM Preview Options, click the RAM Preview button in the Preview panel or press 0 (zero) on the numeric keypad.
To preview using Shift+RAM Preview Options, Shift-click the RAM Preview button in the Preview panel or press Shift+0 (zero) on the
numeric keypad.
3. To stop a RAM preview, do one of the following:
To leave the current-time indicator at the last-played frame, press the spacebar.
To leave the current-time indicator where it was before you started the RAM preview, click the RAM preview button or press any button
other than the spacebar.
The performance of RAM previews performed with the Render Multiple Frames Simultaneously preference selected may be decreased if
antivirus software is running.
Press the asterisk key (*) on the numeric keypad during a RAM preview to place a marker at the currently previewed frame. This is a
convenient way to place markers corresponding to important points in an audio track. (See
Layer markers and composition markers .)
RAM preview a specified number of frames
Press Alt (Windows) or Option (Mac OS) while initiating a RAM preview to preview the specified number of frames up to and including the current
frame. The default number of frames previewed with this command is 5. The preference for changing this number is in the Alternate RAM Preview
section of the Preview preferences. (See
Previews preferences (CS5.5, and earlier) or Previews preferences (CS6) .)
If the current frame is within a backward-propagating Roto Brush span and the Layer panel View menu is set to Roto Brush, then this
command in the Layer panel previews the frames including and after the current frame. (See Roto Brush strokes, spans, and base frames .)
Save a RAM preview as a movie
After Effects can save RAM previews as uncompressed AVI files (Windows) or MOV files (Mac OS). When saving a RAM preview, keep in mind
the following:
After Effects uses the composition frame size and the Resolution setting in the default render settings template to determine the final
dimensions in pixels of a saved RAM preview. If the Resolution setting in the render settings template is Current Settings, then the
Resolution setting in the Preview panel is used. If the Resolution setting in the Preview panel is Auto, then the Resolution setting in the
Composition Settings dialog box is used. The saved RAM preview doesn’t consider the zoom level.
