The fourth week of semi-finalist voting is now over in the 2011 GoPro/Racer X Amateur Film Festival, and in an unbelievably close battle, California's Brandon Biro has come out on top of Canadian Keven St-Pierre. In fact, last week was the closest fight we've ever had ... until this week.

So that means our four finalists for this year's competition are now set. A huge congratulations goes out to Brandon, as well as previous weeks' winners Robert Slate, Nick Gust, and Ian Gutierrez. May the best man win!

Finals voting starts now. All four finalists' entries are posted at the official site of the 2011 GoPro/Racer X Amateur Film Festival, ready for your votes. You can vote on one video per day, and your votes will determine the finishing order of this year's competition. Vote now!
