  Rendering Headache (deadline of course!)

  Posted by Scott Bush on January 8, 2008 at 6:32 pm

  Hi,

  i searched this as I know it has been covered before, but none of the solutions offered seem to be helping.

  I have a DV comp, 720×480 that I need to render. It is only 45 seconds. At about 5 seconds in there is a relatively simple 3D comp that uses one of the 3D text presets, where the letters fly in from behind the camera. At precisely the same frame every time I get the dreaded image buffer error: “unable to create 23116×18533 image buffer…”

  I have tried messing with the memory/cache settings and have tried setting the “secret” settings to purge after every 1, 3 and 5 frames – still the same error.

  i am running a Quad G5, 8GB Ram, OS X 10.4.11. Please help! Seems so simple to render a small comp with a simple preset (and a light). Thanks,

  Interesting new development: if I do a RAM preview, it goes right through the ‘problem frames’ and plays perfectly from RAM. I was even able to render out the ram preview – although I could only get about 20 seconds at as time. Why would RAM preview work but not a render?

  Strange. Have you tried rendering to a TGA sequence, and restarting the render at the stopping point if it dies? That way, you woouldn’t have to re-render the already rendered frames.

  Thanks for the reply, Steve. I haven’t tried that only because I’m going to Final Cut and TGAs are less than ideal. I was able to work around it by rendering about 10-15 seconds at a time with the RAM preview method, but I’d still love to know what the issue is here – seems pretty strange since it is only an SD comp with pretty simple stuff in it.

  Sorry Scott, I left a step out of the process: once you render the TGAs, you reimport them into AE as a sequence, drag them onto the new comp button, and render the comp to a Quicktime movie. The QT render is very fast, since you’re just compressing the TGAs, and no animation or effects are involved.

  This is a common way of rendering from a dodgy machine.

  I wish I could offer more than a workaround, though.
