OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

	# want vi to be the default editor for readline
	set editing-mode vi

	# vi settings
	$if mode=vi
	# normal mode
	set keymap vi-command
	# insert mode
	set keymap vi-insert
	"jj": vi-movement-mode # remap escape

	# want vi to be the default editor for readline
	set editing-mode vi

	# vi settings
	$if mode=vi
	# normal mode
	set keymap vi-command
	# insert mode
	set keymap vi-insert
	"jj": vi-movement-mode # remap escape

	repositories { mavenCentral() }

	configurations { sshAntTask }

	dependencies { sshAntTask 'org.apache.ant:ant-jsch:1.9.2' }

	ant.taskdef(
	name: 'scp',
	classname: 'org.apache.tools.ant.taskdefs.optional.ssh.Scp',
	classpath: configurations.sshAntTask.asPath)

	# put this in your .bash_profile
	if [ $ITERM_SESSION_ID ]; then
	export PROMPT_COMMAND='echo -ne "\033];${PWD##*/}\007"; ':"$PROMPT_COMMAND";
	fi

	# Piece-by-Piece Explanation:
	# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
	# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
	# the $PROMPT_COMMAND environment variable is executed every time a command is run
