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

Here is a high level overview for what you need to do to get most of an Android environment setup and maintained.

Prerequisites (for Homebrew at a minimum, lots of other tools need these too):

XCode is installed (via the App Store)
XCode command line tools are installed (xcode-select --install will prompt up a dialog)
Java

Install Homebrew:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

Please consider using http://lygia.xyz instead of copy/pasting this functions. It expand suport for voronoi, voronoise, fbm, noise, worley, noise, derivatives and much more, through simple file dependencies. Take a look to https://github.com/patriciogonzalezvivo/lygia/tree/main/generative

Generic 1,2,3 Noise

float rand(float n){return fract(sin(n) * 43758.5453123);}

float noise(float p){
	float fl = floor(p);
  float fc = fract(p);

	map.set("a", 1);
	map.set("b", 2);
	map.set("c", 3);

	let obj = Array.from(map).reduce((obj, [key, value]) => (
	Object.assign(obj, { [key]: value }) // Be careful! Maps can have non-String keys; object literals can't.
	), {});

	console.log(obj); // => { a: 1, b: 2, c: 3 }

	This sends the response code and MIME headers.

	Return value is either a file object (which has to be copied
