New Alot of feedback!! Which video is better to promote my iphone game?

Ok my newest iphone game is Atomic 2D Platformer. In the game the main charactor has various powers that I would like to show off. Now if I record on my mac I can only record one level but it comes out sharp , and if I record using my andriod I can record more than one level but its comes out blurry.

Question which video should I use to promote my iphone game?
