Convert MOV to GIF using FFmpeg and ImageMagick

I tried a few different techniques to make a GIF via command-line and the following gives me the best control of quality and size. Once you're all setup, you'll be pumping out GIFs in no time!

Preparation

Install FFmpeg

• $ brew install ffmpeg [all your options]
  • Example: $ brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools

Install ImageMagick

Lesson's learnt building the Guardian

Below is a collection of my favourite responses I gathered from Guardian engineers when asked the question: What have you learnt starting from scratch and building a mobile-first next generation web platform for the Guardian?

• Work with great people.
• Deploy like crazy. This means the team has to control the infrastructure as well as code.
• Design is not a service. Designers have to sit in the team.
• Infrastructure is intrinsically unreliable. Discard and replace is the robust strategy.
• Use your CDN for HTML too.
• Don't always do as you are told.
