The winner of the Best Viral Short Award will receive US $2,000. If you are the winner of an Audience Award, you will receive a prize to be determined by Babel and announced on the Babelgum website. ((Strange.)) If you are the winner of the Stoli Emerging Filmmaker Award, your film will be screened along with other winners and honored at a reception during the Tribeca Film Festival.
