Note:

RAM Allocation Per Background CPU

CPUs Reserved For Other Applications

Todd Kopriva provides information about optimum memory and processor settings on the Adobe website.

Increase this value to leave more RAM available for the operating system and for applications other than

After Effects and the application with which it shares a memory pool. (See Memory pool shared between After Effects, Premiere Pro, Encore, and

Adobe Media Encoder.) If you know that you will be using a specific application along with After Effects, check its system requirements and set this

value to at least the minimum amount of RAM required for that application. Because performance is best when adequate memory is left for the

operating system, you can’t set this value below a minimum baseline value.

Render multiple frames simultaneously

For a video tutorial about using Render Multiple Frames Simultaneously multiprocessing in After Effects, see the video2brain website.

After Effects can start additional processes of the After Effects application to run in the background to assist the main foreground application with

the rendering of frames for RAM previews or final output. These background processes have the name AfterFX.exe (Windows) or aeselflink (Mac

OS).

In this form of multiprocessing, each background process renders its own frame and runs on a separate processor core (CPU). The number of

processes used to render multiple frames simultaneously is never more than the number of processors.

On many computer systems, After Effects CS5, and later can use the virtual (logical) processor cores created by hyperthreading for various

forms of multiprocessing, including Render Multiple Frames Simultaneously multiprocessing. After Effects CS4 and earlier could only use the

physical cores for Render Multiple Frames Simultaneously multiprocessing.

The number of background processes that can run on your computer also depends on the total amount of installed system RAM and the amount

of RAM that is assigned to the After Effects application.

The amount of RAM required for each background process varies depending on your system configuration and compositions.

When the RAM cache (the RAM available for storing RAM preview frames) is nearly full, the background processes cease rendering and

go into a low-memory-usage state, and the foreground process starts rendering—as if Render Multiple Frames Simultaneously were off. This

means that the rendering of a RAM preview will be fast at first, and then the speed will step down as rendering switches to only one processor

core.

Using the Render Multiple Frames Simultaneously multiprocessing feature does not speed up the rendering of all compositions. The rendering of

some compositions is memory-intensive, such as when you are working with very large background plates that are several thousands of pixels tall

and wide. The rendering of some compositions is bandwidth-intensive (I/O-intensive), such as when you are working with many source files,

especially if they are not served by a fast, local, dedicated disk drive. The Render Multiple Frames Simultaneously multiprocessing feature works

best at improving performance when the resource that is most exercised by the composition is CPU processing power, such as when applying a

processor-intensive effect like a glow or blur.

Because antivirus software operates by monitoring every read and write operation, such software can decrease rendering speed, especially with

the Render Multiple Frames Simultaneously preference selected.

After Effects can also use multiple threads to accelerate rendering of a single frame. This form of multiprocessing doesn’t depend on the

Render Multiple Frames Simultaneously preference.

Specifies the minimum amount of RAM that will be allocated to each background process, each of which

runs on its own CPU (processor core). Setting this value lower can allow more CPUs to be used simultaneously with a limited amount of RAM.

However, if you set this value too low for the kinds of frames that you are rendering, then the background processes will fail to render frames at all,

and only the foreground process will be used to render frames. For example, you should not set this value to low value of 0.75 GB if you are

rendering frames with the pixel dimensions of high-definition television or digital cinema.

The optimum amount of RAM to allocate for each of the background processes varies according to project settings (such as color bit depth),

composition settings (such as pixel dimensions of the composition frame), and what effects are applied. For a typical standard-definition

television project, at least 1 GB per background process is recommended. For a typical project with HDTV-sized compositions, at least 2 GB

per background process is recommended for optimum performance. Start with these settings, but run some tests with your own computer

systems and projects to determine the best settings for your specific needs. Digital cinema projects and projects with larger frame sizes require

even more RAM per background process for optimum performance.

Set this value to a number other than 0 to prevent After Effects from using all of the CPUs (processor

cores) in your computer system. For example, if you have a computer with 8 CPUs, setting this value to 2 leaves 6 CPUs for After Effects.

In many cases, performance is improved by using fewer than the maximum number of processors for Render Multiple Frames Simultaneously
