Having shut down Justin.tv on the back of a reported $1 billion Google acquisition, live video game streaming service Twitch is now blocking copyrighted music.

Twitch uses software called Audible Magic which scans videos for music that is owned or controlled by Audible Magic clients. This could take the form of either in-game or background music. Live broadcasts will not be scanned.

“The Audible Magic technology will scan for third party music in 30 minute blocks,” reads a blog post from Twitch. “[I]f Audible Magic does not detect its clients’ music, that portion of the VOD will not be muted. If third party audio is detected anywhere in the 30-minute scanned block, the entire 30 minutes will be muted.”

Affected users will have the opportunity to protest false positives.

That isn’t the only change happening with Twitch. The site’s “save forever” feature is being removed, while users are being encouraged to export footage since Twitch is removing past broadcasts from servers in three weeks’ time.

It’s not all negative, though. Storage for previous broadcasts will increase from 3 days to a maximum of 14 days for users with Archive Broadcasts enabled. Storage is additionally being increased to 60 days for Turbo subscribers, as well as for members of the Twitch Partner Program.

A new Video Manager will additionally let users create highlights, export previous broadcasts, or manage expiration countdowns.
