Making short GIFs of YouTube videos is a pretty well-established practice now -- so much so that there's dozens of websites dedicated to this finest of art forms. But YouTube might be about to make them all obsolete, thanks to a new built-in GIF maker.
At the moment, it looks like the feature is experimental -- the only channel we can find with it enabled is the PBS Idea Channel. In practice, it's pretty slick: on a video with GIF capability, you click Share, then GIF, and can then customise your clip. Maximum length is six seconds, with options to add top and bottom text if needed. Actual GIF creation takes seconds.
It's unclear what YouTube's plans for the future of this feature are, at this stage. But assuming that a site-wide rollout is imminent, you should probably prepare your browser for the impeding onslaught of moving images.
