    Render Not Enough Ram

    420jammer Level 1

      I feel like this must be a well-documented subject, but I'm in a desperate rush to export this project and could not find the information I'm looking for online.  I certainly don't want to spam the board with questions that are well-documented, so if this annoys anyone, please ignore me.

       

      I set my project to render 1920x1080 overnight, but it got to a frame in the middle and turned back an error saying that there was not enough RAM to render.  I tried to copy the exact error, but it disappeared, although it said something along the lines of "decrease memory requirements or increase RAM".

       

      Is there anything I can do to decrease the memory requirements of the scene without changing things visually?  Is there a way to manually make my computer use all the RAM it has on this? I have 8 GB of RAM, so I wasn't expecting a problem.

      Right now I'm restarting my computer and trying again, hopefully to clear as much RAM as possible.

       

      Edit:  I checked my memory settings and all possible RAM is allocated to AE.  I can't give it any more.

          Could simply be an effect using up too much RAM or some of your 3D stuff like large shadow maps. Even damaged source footage can cause this. Impossible to tell. You really can only get to the bottom of such issues by closely monitoriung your renders. It may help to split your render in separate segments in the first place. That way AE wil lfree up as much RAM as possible before starting a new job on the queue...

            It said something about "shadow fragments", so I'm tempted to think you are spot-on about the shadow maps.

            I didn't use many effects, but all the images I used were very high-quality, so I'm guessing that's the problem.

             

            This is a music video, so if I render separately, how will I be able to piece together the entire thing? By re-importing the renders and piecing them together and rendering that? Is that the best way.

              Okay so after reading more, I think it's because the images I scanned in are too large and scaled down in AE.  For my next project, I'll know, but for this project, is there a way to know how to reduce them appropriately and substitute them so that I won't have to do any new keyframes or something? A way that I can just edit the files in Photoshop and have them update to be lower res in AE without affecting their sizes?
