I have a composition on After Effects that I want to render. It is 1 minute 30 seconds long. Every time I attempt to render, a box pops up saying: "The layer exceeds maximum size." I have tried rendering with other formats (e.g AVI, Quicktime, H.264 etc.) but every time it still pops up and says the same thing. Please can someone tell me what this means and what I have to do? Thanks.
Sorry, there isn't enough information to make an accurate diagnosis.
I WILL say this, however: turn off multiprocessing. If you happen to have a big still in your comp -- think 10,000 pixels wide or more -- you may not have enough memory to handle it.
As Dave said, we need a lot more info about your comp settings, render settings, what footage and effects are used and all that. also the exact error message (including all cryptic strings and numerical codes) might offer some insights. The way I see it, some flakey effect is expanding the layer size beyond AE's maximum of 30000 pixels, but we realyl can't be more specific than that...
