Facebook has announced measures to tackle video piracy on its website.

The company said new video matching technology would alert selected content creators if their videos were reposted to Facebook without permission.

In August, YouTube star Hank Green wrote a blog criticising the company over its slow response to video piracy.

Brady Haran, who runs a collection of YouTube channels, told the BBC he still had questions over Facebook’s new approach.Announcing its new approach, Facebook said: “Our matching tool will evaluate millions of video uploads quickly and accurately, and when matches are surfaced, publishers will be able to report them to us for removal.”

The new tool will be available to a “small group of partners” while the company improves the technology.

As well as detecting freebooted videos, the BBC understands the tool will be able to detect when small portions of stolen content are used in another video without permission.

However, unlike YouTube’s content ID system which can block infringing videos automatically, Facebook’s system will notify copyright holders and ask them if they want to remove the freebooted video.
