A new generation of GIFs are here. Apparently its called GIFV. For GIF Video?

They are supposedly smaller in file size, smother, and in mp4 format but replay and look like gifs. I don't know really what they did here, but when I click a gif its URL ends in gifv.
It would appear that they don't embed properly on NS, because they're videos not images...?
