Vid2gif
Useful, but simple, little script for generating animated gifs on the command line.
Uses ffmpeg to do the heavy lifting, all the script really does is take options in one end and feeds em to ffmpeg.
Installation
You need to have ffmpeg installed first, then its as simple as gem install vid2gif.
OS X with Homebrew
brew install ffmpeg
gem install vid2gif
Basic usage
The gem is pretty easy to use:
vid2gif -r 500 yourvideo.mp4 produces a gif, scaled to 500px wide, named yourvideo.gif
For more detailed help, see vid2gif -h
