Update since my last post in November!
Fist off, I've been plagued by this memory issue since updating to CC 2015 on my Mac. I would get random memory error while working on my comps. I notified Adobe and they said that the latest update would fix it. Well it did not, I think it actually made things worst now because it's saying that "AE cannot allocate 0.0010 MB of Ram" or 0.002 MB, and even 0.000 MB of Ram now; at which point I would have to Force Quit the App because the message would cascade indefinitely.
More recently, during renders, the memory usage would go up to 100% before crashing and giving the same message. I assume that this new behavior is do to the length of the comp I'm working on; used to be about 10sec per comp, but now I am working on comps that are more then 1 min long.
Some time I'm working in AE without a fuss, and other time I literally cannot get any work done at all. The error can occur once a day or so, not so bad. But sometime it popping up every 2 min!
I also did some experimentation to find the cause of this issue, or at least some hint has to what is going on:
-My primary workstation is an iMac 27" late 2013 i7-3.5Ghz, 24GB Ram, 4GB GTX780m, OSX 10.10; and my backup workstation is a custom PC from 2009; i7-940 2.93Ghz, 12 GB Ram, 3GB GTX660, Win 7 OS.
-Both computer use the latest Adobe CC 2015, have the same plugins installed, all plugins on both sides are on the same version.
-This week I've been working on a 3min long keying comp (pre-edited sequence rendered out has 1 clip in 1080p ProRes422 - 29.97fps). I was in a rush to get the sequence done asap and half way through the project the memory issue started popping up every 2 minutes or so. I tried purging memory in AE, still happened. Tried purging memory in OS, still happened. I managed to complete the chroma key by working "offline" with "Caps Lock" enable and switching live preview render on and off. Really not an ideal solution but it did the trick.
-Started to render out my comp and that where the memory would start to build up to 100% and crash the App. Not even a quarter of the way thru the render. I was fed-up so I consolidated the project and switched to my PC. Started AE, setup the render to .mov with Animation codec since no ProRes in PC, hit render and 5h later the job was done with an average of 25% out of 12GB ram used! This is insane! I then tried to render to .mov with Animation on my iMac, memory still happen.
-Even tried to play with the Secret menu option, no change.
I usually work with heavy 3D comp inside AE with Element 3D and I can understand that at some point AE can't take it anymore since it's sort of a "hack" of the App that normally can't handle true 3D. But this time it was just a simple chroma key job. I only used three simple 3rd party plugins; Neat video's "Reduce Noise v4" and RedGiant's "Matte Feather Sharp" and "Light Wrap". I used "KeyLight+KeyCleaner+AdvSpillSupp" presets for keyer.
I have to say that I did found a work around that will probably not work for every one. I was desperate to get this issue out of the way so I started scrubbing thru some old Time-Machine backup, found 1 from late 2014 with AE CC 2014 installed. I simply copied the AE sub-folder from the backup Application folder to my computer main Application folder, updated the plugins for AE CC 2014.... and voila!!! I was able to open my AE CC 2015 project in AE CC 2014, make some changes to it and render it without any memory issue!
My 2 cents in all this, I think Adobe really dropped the ball on this one. After Effects CC 2015 for Mac is the least stable App Adobe came up with ever, and I've been working in the Adobe verse since 2001 (AE v5). Is it solely Adobe's fault, maybe not. Apple probably bare part of the blame for making new OS every year for the past 3-4 years which can be hard to keep up with on the "dev" side. I can image they're spending more time on maintenance then actual development. But denying the existence of such a clear and pretty bad issue serve no one. Stop arguing and get to work Adobe!... Please.
