Did you update keylight?

I finally got a look at the error message:

After Effects Error: unable to allocate space for a 720 x 576 image buffer. You may be experiencing fragmentation. In the Memory and Cache Preferences dialog box, try decreasong the Maximum RAM cache option, increasing Maximum Memory usage or both.

Did you try doing what it recommends? Also I’d recommend doing an occasional Edit > Purge > Purge All.

The memory thing helps a whole lot…don’t ask why. I had the same problem with Keylight on my AE and when I droped how much memory it was aloud it rendered fined. I keep my around 512-1GB…. very wierd. Hopefully an update will occur to fix this issue.

Actually, it is a pain why it was set up this way, but an easy fix. I have found that going in to your preferences–>Memory and Cache and set them to the following:
Max Memory Usage: Leave at what it is (mine is at 120%, or equal to 3GB
Image Cache: 33% –This is where the problem most likely occurs, so the lower, the better
Check the Enable Disk Cache, and specify the settings where you would like it to save to

From what I have learned, you do NOT want it to render image cache to your memory. There is not really any need for it. Have it render to the disk. It works so much better

Hope this helps

Disks are slow, RAM is fast. It’s really a balancing act. If you set your Image Cache too high then AE will be pushing the limit on RAM usage and you’ll probably run into instability, if you set it too low then AE is slower to access cached data.

In my case the default setting of 60% has always worked fine.

btw, this also solves the problem for Keylight using AE CS3 on a dual processor. Thanks for the fix, Tim. This was driving me crazy.
