Yes, I’ve got this error too, but I actually AM handling very large images. Basically I need to zoom in on a 7k x 7k image from the full image (scaled to about 20%) to see the very fine detail in one section of it (ending up being 100% scale).
I tried the memory management options with no luck, but…
I’ve found that if I leave the composition un-rendered, then create a Premiere Pro project (of equal dimensions/framerates, etc) then just dump the AE comp on the PP timeline, it builds fine (albeit very slowly).
This is a round about way to do it, so I’d like to hear if there’s better options…
