Youtube has started testing out a new way of letting users share content, allowing them to create animated GIFs and share them the same way they would share full videos. Animated GIFs have become popular tool for online expression, typically used to convey an emotion.

The new new tool allows viewers to select an excerpt of up to six seconds from a video to turn it into an animated GIF, which can then be shared through a direct download link or embedded on any website through code.

For the time being, the feature is available only on a limited selection of videos.

The new feature, if extended to the rest of the platform, could allow YouTube to become an alternative to Twitter-owned Vine.
