running out of memory in render

[Thierry Fortier]

press shift when opening the preferences, you will find a secret panel at the bottoms of the prefs… you can tell after effects there to purge memory each x number of frames in render.

why they make it secret? dont know, its usefull, they (adobe) are stupid hiding it.

good luck!

I had the same issue and I can tell you that this works…..I have 2gb of ram and still had the issue. I set this to purge every 5 frames and it worls like a charm.
I also have issue at the faact that this setting is hidden, and also that nothing is set by default…

yep.
I had the same issue too. There shouldn’t be anything secret about it. lame that they hide that

does AE7 have the secrect setting too?

[Aharon Rabinowitz]

yes it’s in AE7 as well. But be aware it is not something to use lightly – there’s a reason it hidden. Purging can cause a very significant slowdown in rendering if you are using any time based effect, or if you are using any effect or feature that needs to draw on previous frames to work – for example frame blanding or motion blur.

Every time you flush the memory, AE has to recalculate those frames.

I have my purge set to 30 frames, and I find that hasn’t let me down yet.

During the development of Nucleo we found that controlling memory use to be a very tricky subject. Purging would work great in some situations but really kill performance in others. We’re very carfefull about how we purge, we found it best to calculate the proper max memory limit percentage in the AE memory preferences and let AE take care of flushing frames from memory.

:shameless plug:
The good thing is that Nucleo takes care of all that so you don’t have to worry about purge rates or max memory settings.
