I needed 'apple pro res codecs' to export from Ae,
so now that i have apple's 'motion' I'm able to export with 'pro res' codecs on softwares such as motion and mpeg streamClip (type of converter) which is cool.
BUT for some strange reason pro res codecs are still not available to me in after effects. i tried restarting and reloading Ae but that didn't work.
(I posted this on the the conversion page but thought it might be a useful post here)
