Thanks for the feedback guys
Trailer has been ready for few weeks but my single processor and 2GB ram wasn't enough to render it out so I needed to wait and use my friends Quadcore/4GB ram computer to render it. Even that wasn't enough to render it at once so I had to pre-render few parts ahead. And yes, this kind of stuff takes a lot time to do when the composition size is like 20000 x 20000 and every pixel matters :p
I have no idea when the whole highlight is ready because I have to do stuff I get paid for too :p but I keep you guys informed..
@ Pantsman, yes I used AE too.
@ goosepumps, I used QuickTime H.264 because it's the best codec for videos. I will not upload it to flash video sites like youtube because of the poor quality those sites offer.
