40,000 pixels by 40,000 pixels is a giant frame, even for a computer with a lot of RAM---and your computer has a tiny amount of RAM for using Ater Effects.
What are you doing that is generating such large image information? Describe your composition. What are your composition settings? What effects are you using at the problematic point? What kinds of source footage?
Also, you really need to provide more general information when asking questions. What operating system? What version of After Effects?
Thank you for replying, I was getting worried that no one would answer anyway, what I'm trying to do right now is optical flare text and then fade it out through stretching it. However since I dont have the optical flare effect on my computer, my friend rendered a large and small mov for me to use.
Operating system: Mac
Composition setting - 1280px width, 720px height
Pixel Aspect Ratio: Square Pixels
Frame Rate: 25
Duration: 55 sec
I am also using some footages in the background that are all in mp4 format. Each of them are no longer then 1 minute.
*I am also using After Effect CS5*
Sounds likie whatever sub-flavor of MP4 you use is not handled correctly by whatever CoDec and decoded as if it were a huge JPEG. Either your Quicktime iunstall is busted or some third-party QT component is messing things. As Todd said, it might help to know from which camera your footages are and how you get them on your machine.
Happened to me with a text animator and enable per-character 3d. The position of my text was too close to my camera position. I was trying to fly text in from behind the camera text animator 3d position.
mr_epic_peter 's comment above helped me understand why I was getting that error. Thanks!
Did you figure out a work around?
I really want to fly my text in from behind the camera.
This thread has gotten very off track. The original question about buffer size has been addressed. You need to have your assets come close to matching your composition size. 40,000 pixels is a bunch for video so something is out of whack there. Since we know nothing about the assets except that they are mp4 and about one minute long only assumptions can be made. We assume there's something about the mp4 files that may be causing the problem. No one can be sure because specific details, or even the simple details provided by the info to the right of the preview in the Project Panel when an asset is selected.
There is one key bit of system info that seems to have been overlooked by everyone but Todd. 2 GB ram... That's not even the minimum required for any newer version of AE.
Then somehow we got into moving a camera and that lead to a question about moving text past the camera with a per-character 3D move. That one is easy to answer. You just set up your animator so that the z position of the text is at or beyond the camera's z position. The text animator setup should look like this:
Notice the z position of the camera (-1211.1) and the z position of the text position (-1231) 20 pixels past the camera.... - 1211 would probably have worked too but the 20 extra pixels made sure the text came from behind the camera.
I also answered this once before in a different thread.
So, without further information from lir998 I don't think there's much more we can do to help solve the original problem.
Sorry if you feel my comment took away from the point of this discussion. I came across that error message today "After Effects error: Invalid image buffer size (....)", but not the exact same numeric values. I googled it and it led me here. The 1st comment from user (lir998) and the comment user (mr_epic_peter) both pertained to my particular issue. It gave me some ideas on where to start problem solving.
I appreciate your screen capture and the time to address the issue with me. I have a very similar setup to what you've shown in your screenshot . At some point during my prerender when a certain character of text flys in from behind the camera to infront of the camera I get the error again. It's as if part of that character is right on the camera lens...covering it up. Like touching it. From that point on I'm not able to scrub to any point after that without getting the error mentioned. This could be chance and someone else could have character's that may not hypothetically "touch the camera lens".
I'm glad that user (lir998) was assisted with your previous posts and thank you for any assistance you provide fellow artists. I tried some of the things like purging image cache and memory that user (lir998) mentioned in his 1st post. Still wouldn't work.
The error can be triggered by the situation I and user (mr_epic_peter) had. I understood the reason for the error, in my case, based on his comment. This thread helped me and I think that's why we are all here - for help.
If you are getting this error Please post your project file and submit a bug report. There's nothing to the idea of a character running into the lens that should give you this error.
Here's a project file (CS6) that has a big block of text flying directly past the camera with motion blur turned on and centered ecactly through the camera center. Download the project file and see if it does trigger the error for you. If it does not, then look to other things to be causing the crash like effects applied to the text layer or other elements in the composition.
If this sample file does cause the error then please file a bug report.

I downloaded the test file and no issues, im lost as to what to do to rememdy this situation. I have a client waiting on this video.
i hope you can help me.
I know that this thread is very old (before you posted), but i see that your post was less than a month ago. Have you tried the following.
Are you using the CC Light Burst 2.5 effect possibly?
If so, try turning the layer that throws the Buffer Error into a 3D Layer?
This is my initial response, but I just DLed your file and will have a look at it and respond in a bit.
Yup. As suspected, the issue is because of CC LightBurst 2.5 Effects throughout your comp.
One of the effects can be found applied to the "motion blur" layer within the Sub comp: Line-Up > Super 1 > motion blur .
It appears as though whoever set up the project initially was intending it to appear as a light blast into the title after the Audience Rating screen. The main problem you have now is that this effect is used in a lot of locations throughout your project which is throwing your Buffer error all over the place.
An option is to turn off the Light Blast effect everywhere that it appears, however you will lose a lot of impact from the effect. I can not spend the time to go through each layer and comp and find the effect, but the most efficient way is to scroll through and everytime the error comes up, at that frame search through the layers by toggling layers off (if the image goes from black back to visible) then the layer you toggled off has that effect within it somewhere (if seeded within a comp).
Thanks for your responses:

Szalam I've put it on a solid 1920x1080 fx layer and the layers beneath it include several .pngs and a movie clip - all 1920x1080
I've used the effect twice more in the project and they seem to work still - although I haven't tried to edit them since the error came up, also the effect was working without any problem for the 2 days I was working on the project previously and I've not done anything to change it, other than continue to add additional comps to the project.
