Is it just me or does it seem like After Effects gives you more useless error messages than any other program. Every time I use after effects I feel like I’m moments away from either a crash or a prompt to press “ok” to a dialog box of jibberish. I found that mographwiki has been collecting user submitted AE messages. My personal favorite is the now classic question mark. Nothing else… just a question mark and an “ok” button. 

But it’s not all bad. I found a great tutorial for optimizing your AE in response to a very common error. The infamous “Image Buffer” error. Check it out, but use at you’re own risk. Also, I’ve had great success with the secret menu cache settings (see post below for accessing secret menu). Setting it to purge cache after every frame during render, seems to empty out the ram before it moves along to the next frame. Which is very useful.
