It's pretty frustrating how my 1080p video looks like 240p, thus making it really hard to use. Trust me, I might sound like i'm over-reacting but, it's true. This doesn't happen on Premiere because it is 'retina-ready' (2880x1800 resolution)... How come Premiere gets to be 'retina ready' and After Effects doesn't?
I haven't seen any problems. Everything except the extended script tool kit fonts looks great. I posted some screenshots and possible solutions in another thread. I'm a very happy camper. Just make sure your set to more accurate in Preview preferences and that your system settings are good.
