Hey Everyone. I am trying to render a composition that is 720x480. I have a mac pro which is the 3.0 dual processor and i have 9 gigs of ram(Got a really Good deal) . I tried to render out the composition but kept getting After Effects error: could not create 5760 x 3888 image buffer. I kept getting this issue in after effects 7. I read up on the forum and people recommended to try upgrading to after effects 8. I did that as well as up graded the ram from 1 gig to 9 gigs. When i render it out now i do not get the error but after effects tells me it will take almost 2 days to render and then it crashes on me. Does any one have an idea what i can do

Have you tried rendering using the "Secret" settings (Holding down Shift as you open Preferences) and setting a purge after a number of frames during render?

This will often help with these sorts of issues, but will also increase your render times very significantly. The problem, it seems, is that one of your layers is far too big. Have you tried making that layer smaller? Or breaking it into several layers parented to a controller?

yes i tried that as well. Basically the project is a bunch of high rez photos on a cork board that is 5760 x 3888 and a camera moves from one photo to the next. I split the cork-board into 4 pieces so its not not one big file but i am still getting issues.

You are running into this problem most likely because your memory is being fragmented before the render is completed. My guess is that After Effects was installed before the new memory was, and so After Effects is not recognizing all of your memory. Go to the After Effects-->Preferences menu, go to the "Memory & Cache" section and check the settings. Since After Effects still has to render out the entire 5760 x 3888 picture in each frame even though part of it may not be seen, the file size will be larger than most normal 720x480 video file sizes. So anyway, in the preferences settings make sure the Maximum Memory Usage is set to 120% and the Maximum RAM Cache Size for your 9 gigs should be set to something a little over one gig, around 1080 megabytes should be fine. Check: Enable Disk Cache Size and the set it to around 800 megabytes. Hope this helps!
