After Effects (Beta): Unable to allocate 132.563 MB of memory. Either decrease the memory requirements for the rendering of this frame, or install more RAM. (12803 / Unidentified caller.). For more information, see www.adobe.com/go/learn_ae_mem

I'm testing the "beta" of AE and wanted to report this issue.. (which even happens in the official version 25.1) but here it's more constant because as you can see I'm rendering my video and I get this error, and they are just aligned clips without any effect (well, just one, the "twixtor pro" effect) which doesn't take up much space! but still it tells me that I'm out of memory idk.. I have 24 gb of ram of which I have assigned 16 to after effects (leaving 8gb so that windows 11 runs correctly) also even if I add the maximum it still shows up "even though it's a super light project" I'm also noticing that pressing the "space" key to preview has a delay of about 3-5 seconds " it seems that it lacks optimization in the render, I don't know, but I'll show you below how I have my Ae configured and my pc components

here are some screenshots of my after effects settings

Simple proyect i just use clips

I can't tell if the memory requested is 132MB or if the . is a localized version of a , and so AE is actually trying to allocate 132GBs of RAM for a single frame. My suggestion would be look around frame 77 of your composition and see if there are any effects that might be creating really large frame sizes. If you have any effects on that frame, try turning them off to see if that helps.

It does not have any effect.. they are only clips with a single "twixtor pro" effect to make the clips in slow motion.. and they all have that.. so if that effect had been, it should have happened at the beginning and not in frame 77.. because they all have the same effect.

[_Maik]

and another thing that stands out is the delay that is generated when wanting to preview... 3-5 seconds...

[jenkmeister]

It could be the twixtor effect is holding on to memory and after 77 frames of that, it has exhausted the memory your system has available to it. It's very hard to know exactly what is going on. Are you able to share the project? Or turn off twixtor and see if that helps? 

[_Maik]

I have already tried without Twixtor and it went past frame 77 but when it reached 235 it happened again... and so the idea is that I can render the Twixtor effect with the clip because if I don't do it the camera won't be Good! Also, it is something that even happens in the official AE 25.1. I could give you the project but it would be absurd "according to me" because you will not have access to the clips and neither to the "Twixtor" effect. In case you don't have the plugin... In my opinion it must be related to the way in which after effects is managing the ram memory! Well another thing that is usually annoying is when you get This error message has been around for a while and it still hasn't been fixed!   Because of it it is impossible to render! So you have to do it in parts, every 5 frames the timeline is pasted and turns blue and only the green part is rendered and it is repeated simultaneously. And when you try to render the blue part, the same thing happens.. it only renders 5 frames and it starts repeating that 5 frame playback.. which is very annoying.. so this could be it  Regarding how after effects is managing resources 

I could give you the project file but as it highlighted at the beginning it wouldn't work... or I could also put the clips in a folder... but the Twixtor effect would be the problem... what do you say?  (but it should be noted that I restarted and was able to render) but it is an error that persists and it is not the first time that it happens to me... in my case I do not render in MP4 so even if the rendering is cut off and In the middle of a project I can recover what had already been rendered.. but those who render in MP4 and their project takes hours to render and when it has advanced enough.. and And this happens to you when you are about to finish after exhausting hours, you lose your rendering because MP4 is not a "lossless" format. 

(  Sorry if there are parts that you find difficult to understand (my English is not very good)

Is your Beta build up to date? 25.2x122 is the latest. We introduced a new disk cache mechanic for playback which should better handle preview with low memory. I ask, since you're getting the 5 frame problem, and that sounds like an issue from before the changes went into Beta. Assuming you have the disk cache and the preview from disk preference enabled. 

[_Maik]

Mm Yes! I updated it yesterday... the 5frames problem is something that happens to me in version 25.1 because I'm just using the beta to edit. Well, I only used it to import files. "Mkv" since it is the only version that allows it.. I didn't use it for editing for the reason I mentioned about rendering.. which has a delay of 3-5 seconds.. Since I updated it yesterday I was hoping this would change and I'm trying to edit it but it still happens..  

[jenkmeister]

The 3-5 seconds might indicate an issue with the audio settings, or that it is taking that long to render a single frame to get preview started. Though if that's still happening after all the frames are green or blue, I'm not 100% sure what would be causing that delay. 

[_Maik]

I understand that! But that only happens or at least I was used to it happening when I added the "reverb" effect to a long audio (not when it has nothing) anyway. I will continue to see how this update behaves and if I get "low memory" (which is what happens to me in AE 25.1) I will send you the project so you can analyze the problem.

It came out again but this time with "roto brush" @jenkmeister 

[jenkmeister]

In the Memory & Performance preference is a Show Memory Usage button. The next time you hit the can't allocate error, go to that memory usage dialog and grab a screenshot of it and post it back here. Perhaps that can tell us a bit more about the state of things.

Here I leave you a video of what the problem I mentioned about the 3-5 frames and also this memory problem is like... watch it and realize this problem is very annoying!

Thanks. So that looks like 4K comp resolution, potentially at 16 or 32bpc given the warnings I saw on some of the effects. Doing some quick math, that's about 2.8GBs of RAM needed per second. That doesn't factor into account any memory the plugins may holding onto, so that's likely why you're running out of memory, which is backed up by the Twixtor plugin change we tried earlier where you got through rendering 3x the frames. At this point, use the Beta where Preview from Disk Cache is available, or you'll need to work at a lower comp resolution or bit depth (do you really need more than 8 bpc for this)? 

[_Maik]

The composition is at 1080p... not 4k... and the amount of color depth... I like it to be 32 bits because it is necessary so that when adding color to the video it does not generate stains! Or noise.But it is understandable that this would happen if the composition was really in 4k... but I am aware of the limits of my PC... so I work in 1080p... otherwise I couldn't complain.,d From the fact that this happens, it would be reasonable for it to happen if I were editing at 4k
