I've just created an after effects file that is 768 x 1360. the animated video is supposed to function on a 46" plasma screen at a trade show (vertically). My clients have asked for a .swf file, but when they try to play it, it either wont open, or plays a few seconds then the screen goes red. the file size is 1.63 GB. i'm not too familiar with flash files. how should a .swf file be prepared for a presentation like this? Is a .swf the correct way to go?
