Dependencies
FFMPEG 2.6+ Be sure to have ffmpeg installed (>2.6). The easiest way to do that on OSX is via brew install ffmpeg if you have homebrew installed.
How to install
Copy the gifenc.rb file to your scripts directory, or create a new one in your HOME directory: ~/scripts.
Once there, make sure your scripts directory is in your path by editing ~/.bashrc or ~/.zshrc (or whatever shell rc file you are using) and add this:
export PATH="~/scripts:$PATH"
This will add your scripts directory as the first searchable directory in your PATH environment variable.
How to use
$ gifenc.rb -i input.mov -o output.gif -s=640
This will take input.mov and convert it to a gif called output.gif and set its width to 640px. It will scale the height based on the aspect ratio of the input movie.
