AiM codec not converting

Hi -
I'm working on a mac and trying to convert a bunch of ProRez422 to AiM (Superstream, Discard Alpha, 24x) in After Effects and I get an error every time that the Output Module failed.

This setting actually worked a couple weeks ago, now I try it on 2 different machines and get the same results.

I've reinstalled AiM and still no-go. Different files give me the same results.

Any ideas?

I figured it out- as far as I can tell, 24x cannot handle 1920x1080 - we previously used it to render out much bigger files and it handled those great.

1x-12x works fine for that size.

i know this is now sorted but to confirm....

the box in question ( the one that says 1x,2x, 4x, ect ) says threads next to it. if you choose a number which is higher than the amount of available threads on your processor then it will not render as it can find all of the threads you are telling it to use.

very odd- the same two machines were rendering 2664x1158 comps at 24x, but wouldn't work at 1920x1080 at the same thread- only when I went down to 12x would it work.
