I apologise in advance for bringing up such an old issue - and I know there is a lot on the net about this issue. But I am really struggling having just upgraded to CS4
I have projects that were created in After Effects CS3 under OSX Leopard. After much forum reading and hours of experimentation, I managed to adjust all the necessary memory and cache settings so that I could render and preview my projects easily.
I undersood what was needed and how to adjust the settings if the "Unable to allocate space for image buffer...." error ever returned.
In AE CS3 - it ALWAYS worked.
Now I have upgraded to CS4 and Snow Leopard.
Adobe - in their wisdom - have decided to change the memory and cache settings in the preferences dialogue box. I can no longer adjust the settings as I used to.
No matter what I do - no matter how I change the settings - I cannot render my projects.
Why is this now happening.
I don't need to upgrade my machine (Mac - Intel 2 x 3ghz Quad core - 12 gig memory)
Plus the fact that it worked perfectly in AE CS3.
If anyone knows how to reslove this issue - what settings to play with in AECS4 - I would be so grateful.
Thanks in advance
Regarding the changes to the Memory & Multiprocessing preferences for After Effects CS4: The changes were intended to make adjusting the preferences easier. Most people had a hard time understanding the old preferences.
Have you updated to After Effects CS4 (9.0.2)? There are some problems with Snow Leopard that the 9.0.2 update addresses. Can you tell us some things about the composition that is giving you problems, like frame sizes you're working with and other factors that affect RAM usage?
First, check to make sure that Render Multiple Frames SImultaneously is off and RAM To Leave For Other Applications is set to a very low number. You want to give a single rendering process of After Effects all of the RAM that it can take so that it can render the frame that is giving you the error.
