Note: You can locate a previously rendered item or check the destination of a queued render item by expanding the
Output Module and clicking the underlined file path listed below it, or by right-clicking (Windows) or Control-clicking
(Mac OS) the Output Module.
Select the Render option under the Render column heading. The status of the item changes to Queued.

7 Click Render. First, After Effects translates each layer or nested composition into a usable format with its masks,
effects, and layer transformations. Next, After Effects applies and translates any included blending modes. Finally,
After Effects sends the composited frame to each output module to create the final movie.
Note: To view more information about the composition as it renders, click the triangle to the left of Current Render
Details. To view details of a completed rendering, review the log file.

To render with OpenGL

If you have an OpenGL card that supports OpenGL 1.5 or later, you can use OpenGL to render in After Effects by
using hardware acceleration. You can view information about your OpenGL card by choosing Edit > Preferences >
Previews (Windows) or After Effects > Preferences > Previews (Mac OS) and clicking the OpenGL Info button.
Note that only features supported by OpenGL and your graphics card will be rendered into the final movie. If your
card doesn't support advanced OpenGL features, don't use OpenGL to render. For a list of features supported by
OpenGL, see "Supported OpenGL features" on page 140.
❖
Do one of the following:
•
Click the underlined text next to Render Settings in the Render Queue panel, and select Use OpenGL Renderer.
•
Choose Composition > Composition Settings, click the Advanced tab, and choose OpenGL Hardware from the
Rendering Plug-In menu.
Note: Use caution when enabling the OpenGL renderer in a network rendering environment. Inconsistencies may arise
if the OpenGL cards in the network aren't the same.
Note: OpenGL works with 8 and 16 bpc projects only.

Reducing a movie

There are several methods for producing a reduced-size movie from your composition, each with trade-offs between
speed and quality:
Create a new composition at the smaller dimensions, and nest the large composition inside it.
Nest the composition
For example, if you create a 640 x 480 composition, place it in a 320 x 240 composition. Use the Fit To Comp
command to scale the composition to fit the new smaller composition size: Press Ctrl+Alt+F (Windows) or
Command+Option+F (Mac OS), and then collapse transformations by choosing Layer > Switches > Collapse. The
