REFACE is the Face Swap App Create hyper-realistic face swap videos & gifs with just one selfie 

Want to turn something on YouTube into a GIF, but don't want to futz with downloading third-party apps or digging around for an online converter? Here's a handy trick: just add 'gif' to the beginning of the URL. 

For example, you'd turn: 
www.youtube.com/watch?v=dQw4w9WgXcQ 
into: www.gifyoutube.com/watch?v=dQw4w9WgXcQ.

Then set the GIF length in seconds using the slider and and hit enter. Here's an example I made. ( via: Techcrunch )
