After Effects error: Keylight Out of Memory
on Oct 27, 2009 at 6:08:03 am

Hi all,

I'm trying to render out a composition in AE CS4, and within seconds of hitting render, it fails with the message "After Effects error: Keylight out of memory. (4)". This also happens when trying to view any one frame at full res.

The source footage is a Quicktime movie with the Apple ProRes 4x4 codec, resolution 3840x2160, and I'm rendering to 1080p.

Machine specs: Processor: 2 x 2.93 GHz Quad-Core Intel Xeon, 8 GB RAM.

Open GL is off, as is multiprocessing. I've tried enabling disk caching. I've also tried enabling purging frames in the secret preferences. I've quit all other applications. All to no avail.

I have upgraded to the latest version of Keylight (1.2.10).

I've definitely used Keylight before on even larger footage in larger than 1080P, complicated comps and not had this problem. That time I was using DPX sequences rather than quicktime; I wonder if that's easier to process than ProRes 4444 quicktimes? I'd rather find a different solution than having to re-render all my source footage, though. Any ideas?

Thanks for reading.
