image buffer errror (I can’t render out!)
I composited multiple photoshop images into a massive 30,000×22,500 pre-comp. I put this in a 800×600 composition in order to scale it up to simulate “zooming in” on minute detail in the image.
I animated the 800×600 composition with the preview monitor set to quarter-resolution, but when I set it to “full,” it says “After Effects error: could not create 30,000×22,500 image buffer (7::39).” The same occurs when I try to render out the 5 second clip using “Make Movie.”
I know I could decrease the pre-comp resolution, but then I would have to re-do the animation which I’d like to avoid since I carefully used the graph editor to tweak the keyframes perfectly.
I’m using a Mac G5 and AE 7.0Thanks very much!

this is a common problem I have run into a lot also. There is purge feature in the secret menu of after effects you can get to it by holding down “shift” and going “After Effects”>preferences>let go of shift>And go to the scroll down tab and you should see secret, i would put in about 15 or 30, but this does not always work, your best bet would be to shut down the computer and restart it. This usually works for me.

How much RAM do you have? Sounds like you need a load of it for resolutions like that. You could also try purging all caches before doing a preview or render – to maximise that aswell, also try skipping a frame or two on RAM preview (shift+RAM settings)
There’s the other usual workarounds like pre-rendering whatever you don’t need control of at the time of this preview, reduce res of layers if poss and their full res is not needed. Try rendering with caps lock down, so the preview window doesn’t take up memory updating. Ther’s also a secret or ‘schecret’ menu you can get to which I can’t remember (search schecret on the cow) which purges X amount of frames as you render to free up RAM. One of those should do the trick..

Thanks for the tips everybody, but it’s still not working.
It’s just that one huge 30,000×22,500 pre-comp within a 800×600 comp so I tried pre-rendering the pre-comp but it still immediately says “image buffer error” before it renders even 1 frame.
I tried that secret menu “purge frames” idea but since it won’t even render a frame, I guess that’s no use.
I put on caps lock to disable the preview monitor also.
I hope I don’t have to resort to reducing the resolution of the pre-comp because I’d have to re-animate it which would take awhile. Also, I need that resolution to be able to “zoom-in” on specific detail using the 800×600 composition. Why does After Effects allow me to make a composition that it can’t render out at full-resolution?Any other ideas?
If not, thanks anyway for the help everybody. -
Don’t know the answer to that one I’m afraid, other than try it on a faster machine with more memory. AE is letting you have a comp of that size because somewhere there is a machine that can render it…it doesn’t know you’re machine can’t since the software is not tied to the hardware’s limitations in that way.
What you could try as a workaround is to enable caps lock before loading the comp in question, then load it up at quarter res or something with your quality switches down – it will be difficult to work with, especially when you need to determine how much mo blur/interlace flicker you need to apply (for a picture that size I’ll bet you’ll get some really nasty flickering on a TV screen when it’s zoomed right out) but you should still be able to render it out at full res using the secret purge menu and caps lock..Let us know how it works out.

I ended up just reducing the pre-comp to 15,000×11,250 and re-animated it with the graph editor. I knew from the start I might have to do this, but I tried everything else. The huge pre-comp image is a composited drawing of a landscape I scaled-up to simulate the camera “falling” from the sky. The hard part was tweaking keyframes with the graph editor to make the acceleration look realistic.
Anyway, now I know to test the image with the preview monitor set to “full” before I animate at half or quarter preview resolution so I know I can export.
I still learned some new stuff from everybody’s tips, like the “purge frames” feature in the secret menu and disabling the preview monitor with caps lock.Thanks to everyone for their suggestions!
