MixBitChad Hurley and Steve Chen, co-founders of YouTube, have launched a video-stitching app called MixBit, through their company Avos Systems.

The MixBit app lets users record, edit, and publish videos as short as one second or as long as an hour – right from their mobile devices. Users can also collaborate on the MixBit.com video site to remix content uploaded by the community.

Videos are recorded in multiple clips as long as 16 seconds each. A finished video can include as many as 256 clips, for about an hour in total length.

The MixBit app is currently available on iOS (iPhone, iPad and iPod touch). The Android avatar of the app is expected to be available by the end of September 2013.

Avos is headquartered in San Mateo, California, and has development offices in Beijing, China and Dunedin, New Zealand. The company is backed by Google Ventures, Innovation Works, Madrone Capital and New Enterprise Associates.
