Creating gifs from quicktime screencasts for use in github comments / pull requests.

gistfile1.md

Grab the dependencies first.

brew install ffmpeg

Record your screencast video with Quicktime

Example

Put this function in your .bashrc/zshrc

I like to put the converted gif into my screenshots folder, change how you see fit

makegif() {
  print "Making a $1 gif in ~/Screenshots"
  ffmpeg -i $1.mov -vf scale=640:-1 -r 10 -f image2pipe -vcodec ppm - | convert -delay 5 -loop 0 - ~/Screenshots/$1.gif
}

Use said function on the file, note I'm omitting .mov extension

 makegif my-screencapture-video
