Facebook has released a new app for making videos that it thinks can win over the competition by allowing collaboration among friends.

The company on Wednesday released Riff, a mobile app that lets people create short videos and then share them with friends. A video creation and sharing app alone is not unique—other services like YouTube, Snapchat and Twitter provide some other apps for this—but Facebook is hoping to distinguish its app by adding a strong collaborative element to it.

After someone creates a video in Riff, that person’s Facebook friends can add to the video with a video of their own. From there, friends of the friend can add to it, and so on. This has the potential to give the video a communal effect, reminiscent of the Our Stories function in Snapchat that lets people watch videos taken by others during an event or over a period of time.
