Soapbox -- Microsoft's answer to Google's YouTube -- was opened up to a public beta last month with all users allowed to upload videos. That privilege now only applies to registered users, and the site is not accepting new registrations, said Adam Sohn, a director in Microsoft's online services group.

Microsoft is trying to constrict Soapbox's growth while it gains control over its 45,000-strong video-clip library in a sensitive legal environment, Sohn said.

Viacom's $1 billion lawsuit against Google, filed March 13, over copyright content on YouTube "certainly helped" Microsoft's decision to slow down Soapbox.

Microsoft will use technology from Audible Magic that will filter uploaded videos and block those with content under copyright, Sohn said. The company is also creating software for copyright holders that will help more easily identify if their material is online and streamline the notification process.

Microsoft -- as well as Google -- will remove videos under copyright if notified by the copyright holders. That process, however, often involved someone writing down URLs and supplying them to the company, Sohn said.

The tool could take the form of a password-protected portal, but the system remains under development, he said. Microsoft plans to reopen Soapbox to all users within 30 to 60 days, Sohn said.

Sohn wouldn't say how many video clips have been removed so far from Soapbox, but "that it's an ongoing thing, it happens all the time."
