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

	APP_PATH="${TARGET_BUILD_DIR}/${WRAPPER_NAME}"

	# This script loops through the frameworks embedded in the application and
	# removes unused architectures.
	find "$APP_PATH" -name '*.framework' -type d \| while read -r FRAMEWORK
	do
	FRAMEWORK_EXECUTABLE_NAME=$(defaults read "$FRAMEWORK/Info.plist" CFBundleExecutable)
	FRAMEWORK_EXECUTABLE_PATH="$FRAMEWORK/$FRAMEWORK_EXECUTABLE_NAME"
	echo "Executable is $FRAMEWORK_EXECUTABLE_PATH"
