Join Chris Meyer for an in-depth discussion in this video Exploring the Global Performance Cache, part of After Effects Apprentice: 02 Basic Animation.
- [Instructor] As of version CS6,…After Effects has made some major changes…in the way that it manages the cache…of your previously rendered and previewed frames.…After Effects refers to this as its global performance cache…and that encompasses both RAM and disk based caches,…and these are the subjects I want to cover…in this sidebar movie.…As you may know by now,…when you have performed a RAM preview on a composition…this green bar will indicate frames…that have been cached or previously calculated…and stored in RAM.…
They need to be stored into RAM…so that After Effects can play them back…in real time for your preview.…Any change you make to your composition…will cause this green bar to be erased,…indicating it no longer has proper frames stored in RAM.…For example, if I change the initial scale…of the snowflake layer to 95%,…you'll see that the green bar has disappeared…just for the range in between those two scale key frames.…From the second scale key frame onward,…the value remains the same,…so there's no need to invalidate…
