I need a short (30 seconds) stock video without usage limitation

I need a short video with two or three persons where one is playing a game on his smartphone and is winning the game.
Just like this video, including the slow-motion: http://www.shutterstock.com/video/video.html?id=4501190

I could use this video from shutterstock, but they force me to put a text in the video stating "the person so pictured is a model and is used for illustrative purposes only".

So I need a video without any usage restrictions.
