Making videos into GIFs on the command-line with gifify I like making gifs.

You also probably like making gifs.

It's a thing we do.

On a regular basis I'll have video from television shows or movies or other video I've taken myself like screencasts that I want to turn into a gif.

Turning video into a gif can be done using online services, but I need a quick way to do it on the command line.
