Chapter 8. Playback, Previews, and RAM > Frame Rates of Playback versus Preview

Frame Rates of Playback versus Preview

Your computer displays frames by temp orarily loading, or caching, them into RAM. When the cache becomes full, old frames are purged as new frames are added.

Using the standard playback mechanism, frames may take longer to load into RAM at first, but once they are cached, they play back more smoothly. Even then, the performance depends largely on how much processing the frames require and your computer's processing speed. Less demanding frames play back readily, while more memory-intensive frames may chug along only as quickly as your computer can handle them. You can see the frame rate you're getting in the Time Controls palette (Figure 8.1).
