GIFs for my homies
With Homeslice, you can create animated GIFs from almost any video on YouTube or Vimeo in a few seconds. Just launch the extension while watching a video, select a chunk to slice out, and create your GIF. And if you're one of those control freaks, you can even set the dimensions, frame rate, and color depth.
NOTE: Homeslice only works when you're watching a video on the YouTube or Vimeo sites.
