Did you ever want to share a clip of a streamer who puts his face into a pie or shows how NOT to drive in Borderlands?
Now you can, in certain partnered streams. Click the button and it will create a clip of the previous 25 seconds and the upcoming 5 seconds. The clip will be shown in a new tab. From there, you can share your clip. You get credit for creating the clip and the streamer gets extra promotion.
On Twitch Support there is a guide to help you get started.
