Question

32 bit EXR img sequences still max out memory and crash.

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.

    Hi All,

     

    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.

     

    Thanks!

    Hey @jenkmeister17177426, @fnordware & @dermot_faloon.

    I'm also experiencing fatal memory leaks with 32bpc EXR files (HD) that are using Extractor to resolve 47 channels per file. It occurs in AE or using Media Encoder. I'm wondering if the leak is happening with Extractor? When I have time to test I will, but do you know if this happens when the channels are written out to separate files? If the bottleneck is with the unpacking of the EXR in AE, I'll gladly clutter my files with more pieces just to save me from the crashing until we can get it sorted. Brendan, if you read this, you've been so helpful over the decades, please know that all of your hard work is so greatly appreciated.

    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.

       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,
      Krzys

        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!

          sorry, spoke too soon. while it does seem like an improvement, AE can still hang the entire system when using large .exr sequences even without filling all 64gb of ram on the system. after a minute or so, the system recovers but all windows appear empty until a refresh or a restart of the program. task bar is transparent until I move or resize it, desktop shows no icons until I toggle the "show desktop icons" option on and off.
          have not had it happen to me while rendering, only previewing...

          Hi @dermot_faloon,

           

          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 aebugs@adobe.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/bcc63db88e920ad36ff2802a21dc732820211123120659/c07493

           

          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.

          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.
