Adobe After Effects Help
Using Help | Contents
When a memory error message is displayed, temporarily remove effects from the
•
project in order to finish rendering.
Note: Although After Effects can run with RAM-extending utilities, such as RAM Doubler,
use of such utilities significantly slows the application and is not recommended. The use of
virtual memory on Mac OS systems is also not recommended for the same reason.
Running After Effects on multiprocessor systems
When running on a Windows NT, Windows 2000, or Mac OS multiprocessor system, After
Effects employs an MP plug-in to make use of the added processing power available. With
this plug-in, a multiprocessing system previews and renders certain operations much
faster than single processor systems. The MP plug-in accelerates movement, rotation,
motion blur, blending modes, and other computation-intensive operations, including
plug-in effects such as Compound Arithmetic and Bevel Alpha.
The degree to which the MP plug-in improves performance depends on the type of
operation being performed. Memory-intensive operations are accelerated only minimally.
Performance improvement also depends on system variables, such as the operating
system, the type and number of processors, hard drive type, and compression. To
determine the impact on rendering speed, render a project using the plug-in, move the
plug-in out of the Plug-ins folder, render the project again, and compare the rendering
times.
Using the Windows MP plug-in (Windows only)
The MThread.aex plug-in enhances After Effects performance on multiprocessor systems
under Windows NT. The Adobe MP Accelerator plug-in is installed automatically during
the After Effects installation process.
Using the Multiprocessor Support plug-in (Mac OS)
The Adobe Multiprocessor Support plug-in enhances After Effects performance on
Mac OS multiprocessor systems, such as Apple G4. The Adobe Multiprocessor Support
plug-in is installed automatically during the After Effects installation process.
