YouTube was designed to make it easy for people to share videos, but its co-founder Chad Hurley tells me that “we were never able to provide tools for people to create better content.” He and fellow co-founder Steve Chen, who now run a company called AVOS Systems, hope to fix that beginning today with the launch of MixBit. They’re offering a free mobile phone app (initially for iPhones, one for Android coming soon). It enables users to shoot 16-second clips and then drag and drop as many as 256 of them into a sequence to create a video lasting up to an hour, which can then be published. The goal is to make it simple. Unlike Vine and Instagram, MixBit won’t offer filters or effects, and it only uses audio recorded by the phone. Users also can edit videos at a web site, MixBit.com, and share clips with others or keep the whole thing private. Hurley says that “at some point” MixBit will have ads but for now “we really are focused on the community and solutions and don’t want to introduce things that alienate the reasons why people are participating.” He has spoken to “a few friends in the movie industry and they’re definitely intrigued” by the story-telling platform. AVOS is backed by Google Ventures, Innovation Works, Madrone Capital and New Enterprise Associates.
