Setting image caching preferencesAs you work on a composition, After Effects temporarily stores rendered composition and source images in RAM, so that previewing and editing can occur more quickly. For example, once you view a specific frame in a composition, that frame is stored in RAM until you run out of memory or until you edit the composition in some way that affects that frame. You can control how After Effects stores images in RAM by setting different image-caching preferences. The controls available differ on Mac OS and Windows systems. To specify image caching (Windows):
Note: The Image Cache Size setting directly affects the number of frames that you can play back in RAM preview. Increase the value to play back more frames. Decrease it if you notice that your RAM previews jerk and halt during playback. This jerky playback often occurs because of virtual memory paging activity, which is affected by the memory usage the other applications you have running. To specify image caching (Mac OS):
No matter which setting you choose, After Effects makes the image cache more compact when you choose About Adobe After Effects, when you perform a RAM preview, or when you are between renders in the Render Queue. |
