I notice this technique while playing Dino Crisis 2 on the PlayStation. This console system surely has a poor graphic capability! But the game was able to render many cool CGI scenes (not video clips, my friends), as smooth and anti-aliased as if they''re movies! All of this clips were build up on-the-fly with 3D objects, just like any other action scenes. So, this is the tip: the game''s producer used the motion-blur technique to make the character''s movement smoother, more cinematical, and the whole scene looks anti-aliased! This''s so effective and very cheap in processing requirement. Hope this idea can help..
