All versions of the new AE are unable to deal with longer sequences of EXRs (DWAB). Tested on 22.1.1 beta too and still broken. Fails on all of our teams Windows 10 machines (20H2) 64Gb memory. Very disapointed as this is the format used by most 3D artists doing serious colour work and post. Oddly the same AE file brought into premiere to render to Proress4444 handles it just fine. Using this inside AE is impossible as it fills the RAM in the backround till the machine struggles to function. It ignores the memory prefs, dropping to half (32Gb for remaining OS) it still uses 99% memory and falls over. EXR files created in C4D with alpha. Can supply link to test project if you wish. Please fix this issue as it has caused many days of problems in our company. We have resorted back to older AE to render the job but this is poor.

Having the same issue here. Mine has happened on 2021 and 2022, I actually was hoping 2022 would help fix it...but no.
I will contine to try each Beta when they drop, its not good enough tho when Premier can handle it fine (the same AE file), then again Premier has Pro written beside it, maybe we need After Effects Pro. Seriously tho, this is a big issue for my workflow and glad to hear somebody else is having the same problems.
Its really bad, all of our 32bit EXRs on all of our comptuer systems just fill up 128gb of ram in minutes and it stutters the system or crashes them. But it renders perfectly no issue out of AME...This bug has been extremely stressful.
Can I ask that you send me your hardware setup from hwinfo or similar? I am keen to try and troubleshoot this as its causing me great issues at the minute and I only have the same type of workstations to try. See if its the type of memory, board, or some other thing.
Thank you for reporting this issue, and our apologies for the frustration. If you could send a us a link to a test project with the EXR assets, that would be ideal so that we can see and debug the problem in action. Feel free to either DM it to me here via the forum messaging or send the link to email@example.com. Please let us know here if you send it to that email as we need to check the inbox manually.
Do you find that this issue is worse in 22.0/22.1 than in previous releases? If you disable "Cache Frame When Idle" in the Composition menu under "Preview", does your RAM continue to fill?
Thanks very much for any additional information,
- John, After Effects Engineering Team
Hi John, here is link containing a small test project - didnt include the large one I have but its some random bits on a timeline that take down the PC just the same. https://streetmonkey.wetransfer.com/downloads/6e192ef26c7eeb96833d4c526d3e4b0920211123120659/bcc63db...
I have resorted to going back to versions of AE still installed without the multriframe, but this isnt ideal either. This zip also includes my harware and a video of the issue happening (although its a earlier build of AE than whats running now). Tried the latest Beta this morning 22.1.1 and still no ability to work with EXRs without the memory issue.
Hi John, just a follow up - did you get my project ok? Doing some futher testing I agree with Justin above that both 2021/22 have considerable memory issues on my PC and all the others in my studio (same hardware). I notice that taking some projects over to my mac laptop I use to Parsec in, (a 2012 Macbook pro 8Gb memory) I find the performance to be suprprisingly similar to my work PC, I can rely on my old mac laptop to finish the renders too. So something is very very wrong with the windows build of AE, I assume its AE as I can drag into Premiere and the issue doesnt happen, but thats not good enough when I need to work inside AE. I have also tried a fresh install of windows 10 and Adobe suite, same memory issues and general sluggishness. I have used AE since 94/95 and used all versions, these last two I feel push this PC in some very weird ways. This may be some hardware conflict, I will see if Justin could give a breakdown of his setup to see if anything is similar.
Windows 10 - 128gb ram (which it fills entirely in seconds but claims to only fill less until the system stutters.)
This happens with both 2022 and 2021. Auto cach or not.
Definitely seems related to EXRs, not just 32bit. I just tested it with 16bit. And tested it working in all 3 modes (8, 16, 32)
AE seems to show that its doing nothing wrong, but my ram continues to fill till it hits a wall and stutters my machine. Happens on 4 other computers in the office.

I believe a friend of mine found the solution, or at least it has completely solved it for both of us.
Rename the openexr.aex file in (...Program Files\Adobe\Adobe After Effects 2022\Support Files\Plug-ins\Format) to "openexr.old" and download the proexr plugin https://fnordware.com/ProEXR/ here to replace it.
I am completely steady now.
No clue whats different between the two, but if you need to get work done like I do right now, give it a shot!
Download the ProExr plugin from www.fnordware.com/ProEXR/ and replace the OpenExr plugins in the "Support Files\Plug-ins\Effects" folder with the ones downloaded. There are 3 files. EXtractoR.aex, IDentifier.aex and OpenEXR.aex.
This fixed it for me. Best of luck,
There should be an updated version of EXR starting in 22.1.1x70 and now in the 22.2 builds. Hopefully that resolves the issue and you don't have to copy in the ProEXR ones by hand. Please let us know if you still see the issues though!
Downloaded 22.2 Beta today (30/11/21 UK) and opened my test file above - opened task manager and watched it simply fill up and melt down windows when hitting 99% of my 64Gb memory. I have yet to try hand installing etc as I wanted to keep this vanilla and ensure it was all AE without tinkering. At this point I think I may have to try the advice above - I will be avoiding the newer AE builds for a while yet it seems. Maybe someone advised you this was going to be changed but not yet? I will continue to try each Beta and see. By chance I am working on a non 3D job at the moment but will try the PROEXR workaround later this week and post my thoughts while I wait for this essential element of AE to be fixed.
That's super helpful to know. We will chat with the ProEXR developer and see what we are missing with the latest integration to get this fixed asap.
Thanks for the project, @dermot_faloon. I rendered it out the Render Queue and sure enough, my RAM filled up.
Nope - still broken.
I have 64 GB of ram and reseved 12Gb for other apps within AE (i normally leave around 8 if its working). Opening the project and leaving it on build 22.2.0(build17) it still hits 99% memory straight away, and obviously stability and function falls over. Will keep trying each Beta as it comes out. Been resorting to old builds of AE to get things done. Next 3D project I will try replacing the poor Adobe AE EXR plug in code and update here with results. Can I ask if you are using windows 10? I have a colleague who managed to render this on their Mac - it didnt fail.
I was testing on Mac. Will try on Windows.
Thank you for perservering with us on this one. If you haven't already, please try lowering the amount of memory given to After Effects and see if that allows your renders to complete. Perhaps start with 40GB to After Effects on a 128GB machine.
Here is the latest update using build 22.2.025 (8th Dec)
Windows 10 64GB Ram
Tested reserving 12Gb so AE has 52Gb available. Quicky spiked to using 99% of teh memory and causing all sorts of stability trouble. Force Quit and restarted.
Tested reserving 32Gb so Ae has 32Gb available. It renders out fine although looking at task manager the memory usage for AE sat around 45-48 Gb of usage, not 32 as instructed.
I hope you get this resolved and it doesnt become one of those issues like Auto Save not autosaving every (x) and just doing it at random.
I will continue to try each Beta but I think you need to warn users to reduce memory to get some form of stability until you figure out what is wrong. This affects peoples ability to manage project and deadlines over the busy Christmas/New year advertising period.
Latest test on Beta 18.104.22.168 - 9th Dec
Windows 10 64Gb Ram
40Gb for AE and 24Gb reserved still stressed the sytem too much at hit 99% causing issues - lowest memory use around 54Gb used by AE.
32Gb for AE and 32Gb reserved was more stable - still used way beyond the 32 it is supposed to stop at but managed to finish - froze and flashed a few times but completed in a fair time. Cant say about other projects with mixed assets and effects use as I am still waiting until it shows itself to be stable enough for practical daily use.
Thanks for keeping after this, @dermot_faloon. I've gotten a batter handle on what's happening. The version of the OpenEXR plug-in shipping with the latest AE is handling its internal caching differently than the posted version, in hopes of working better with Multi-Frame Rendering. But there are some issues with the new approach, as you've discovered.
Try this new build of the plug-in for Windows and hopefully you'll find it no longer fills up your memory. Once it's been tested, we'll get it into a future AE.
Latest test on Beta 22.214.171.124 - 9th Dec using seperate EXR format plug in supplied above.
64Gb Ram Windows 10
32 Gb reserved and 32Gb given to AE - rendered fine in 12:58 and used approx 30Gb Ram, never over.
12 Gb Reserved and 52Gb given to AE - rendered fine in 9.54 and used approx 49Gb, never ran over.
So it looked to be working as it should, this test does not have effects applied but I assume this will hold the same.
CPU looked to have maxed out too as it wasnt fighting as much with the memory.
Looks to have been fixed. Will check on the latest Beta and update.

We now have the updated bits from @fnordware integrated into the latest AE beta builds. We'd love to get some external testing to confirm the integration. Try out build 22.2.0x85 or later and let us know if things are better for you.
