@nexdrew could you please add this to the gifify repo as a PR? very valuable

@vvo and @nexdrew, here's a PR that does it in a curl one-liner: vvo/gifify#46. Feedback?

For anyone else interested, installing gifify locally works pretty well too.

$ npm install --save-dev gifify

… in your package.json:

"scripts": {
  "gifify": "gifify"
}

And can be run from command line like so:

$ npm run gifify -- -o test.gif test.mp4

… or js script within package.
