Hello, Iv'e got a problem.
When im about to preview my compositions it wont render whe whole comp.
Only about 9 seconds.

Im wondering, how may I fix so I may preview the full comp?

I was able to do that before I reinstalled my computer.
I remember I had this problem before aswell. For about a year ago when I first insalled my AE.

I cannot remember how I got it to work though.

Thanks for your help in advnace.

It does not matter if your a beginner or professional. You have always something new to learn.

RAM preview works by caching as many frames as possible into the RAM that you've allocated to the foreground After Effects application. When the RAM preview cache is full, After Effects plays the frames from the cache.

If you want to make RAM previews longer, you can do all sorts of things, but they basically break down into two categories: allocate more RAM to After Effects or reduce the amount of memory that each frame takes up.

More information about RAM preview, memory, and performance can be found in these sections of After Effects Help:

Preview video and audio

Improve performance

In the end, realize that RAM preview is not suitable for playing an entire long composition at full resolution and full frame rate. Sometimes, you just have to render out a test file to see how things look.
