• The composition uses an effect with a temporal component that renders much more quickly when the rendering
process has access to a cache of previous frames. These effects include some effects with a Temporal Smoothing
option.
• The composition uses an effect with a temporal component that requires frames to be rendered in strictly sequential
order.
If a composition uses any of the following effects, the composition will not be rendered with the Render Multiple
Frames Simultaneously multiprocessing feature:
• Auto Color
• Auto Contrast
• Auto Levels
• Cartoon
• Lens Blur
• Particle Playground
• Shadow/Highlight
Note: Some third-party effects—such as CC Time Blend and RE:Vision Effects Video Gogh—are also incompatible with
the Render Multiple Frames Simultaneously multiprocessing feature.
Performance
Improve performance
You can improve performance by optimizing your computer system, After Effects, your project, and your workflow.
The best way to work faster overall is to plan ahead and run early tests of your workflow and output pipeline. (See
"Planning your
work" on page 33.)
Lloyd Alvarez provides the BG Renderer script on the
export compositions in the background while you continue to work in After Effects.
GridIron Software provides Nucleo Pro 2, which improves rendering performance in After Effects in several ways. For

Improve performance before starting After Effects
• Make sure that you've installed the current version of After Effects, including any available updates. To check for
and install updates, choose Help > Updates. For more information about updates, go to the
the Adobe website.
• Make sure that you've installed the latest versions of drivers and plug-ins, especially video card drivers. To
download updates for drivers and plug-ins, go to the provider's website.
• Quit applications that are not necessary for your work. This may include some applications that start automatically
when the operating system starts.
• Make sure that your system includes a display card that supports OpenGL 2.0 or later. Though After Effects can
function without it, OpenGL accelerates various types of rendering, including rendering to the screen for previews.

OpenGL" on page 703.
