AE not enough memory

[MartinMulcahy]

I started working on very large After Effects files, and I keep getting a message that the application is out of memory. I clear the cache often, and set the maximum to 500GB..I have 600GB free space on a 1TB iMac. I only have After Effects open, and allotted 13GB of 16GB total RAM memory (it does not let me go any higher) I have assigned the disk cache memory to a 1TB external SSD drive.   I have a 16GB iMac and Apple has made it so you can no longer upgrade. My question is what else can I do to get After Effects to run. I have no other applications open

What is the comp size?

what kind of layers, video footage and animation you are using in your projects ?

[MartinMulcahy]

thanks Mohammad. the master comp is pretty large, 8192 x 8640, with 23 comp panels within, but only 4 layers each, with slight scale and position animation of giant headshots. Should I save it in two parts maybe? i had no problem making edits to this same project on my older iMac intel with 32GB RAM. But now I have the 2023 M3 with 16GB unified memory.

The master comp size is pretty big, I am having 64GB of Ram, when I am working on huge comp I got a the same message, so What I used to do is, I created a keyboard shortcut for " Purge memory and disk cache" so I use it frequently and everything is running smoothly.

Even I am getting the same issue while I was rotoscoping a 1 minute video to cut my subject from background. I have the same cofiguration.

bummer, what is your workaround? Others have said this is an Adobe issue rather than a Mac issue? still its so frustrating.

Using beta AE v25 seems to be working! Its weird because AE v24 uses a whopping 95GB when opened. but the Beta AE v25 only uses 15GB, so I am able to work without crashing. THANK YOU!
