After Effects RAM and render
I have a lot of RAM and I am using CS4. I noticed when rendering, AE says using 30% or whatever of 3.0 GB. AE can use more ram as I have much more available and I have it set up in memory for it to do so. Is this just for RAM preview and work and not rendering? Is there something I am missing?

No, I have 12 gb in my computer, but AE says “30% of 3 GB” when it is rendering. I have no idea why this is.

That message that you get on startup is misleading to the point of being useless. There’s really no value at all in knowing how much RAM After Effects is using to start up.
Regarding the 3GB part: After Effects CS4 is a 32-bit application, so the theoretical maximum that it can use (per process) is 4GB. The operating system actually hogs some of that, so After Effects really gets a maximum of 3GB allocated to the foreground process. There’s a lot more detail in this section, including the comments at the bottom of each page.
If you use Render Multiple Frames Simultaneously multiprocessing on a 64-bit operating system, then After Effects will start additional instances of itself that each get to use a few GB to render frames in parallel. So, your 12GB won’t go to waste.
BTW, the 4GB per process limitation of 32-bit applications is why you should be happy about this: “Future versions of After Effects will be 64-bit”

Thanks!
So, what you are saying is that percentage of GB being used when rendering is not accurate?
I never was concerned about the message at startup, but I understand what you are saying and why you mentioned it.
