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:

I recently had the following problem:
We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like
ssh -L 3306:localhost:3306 remotehost
Note: total experiment and hack, looks nasty, could be awesome:
kitchen.local.yml
into $HOME/.kitchen/config.yml
brew install polipo
, with Ubuntu: apt-get install polipo
)polipo-start
and polipo-console
somewhere useful (perhaps $HOME/bin

Grab ffmpeg from https://www.ffmpeg.org/download.html
It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons.
The most trivial operation would be converting gifs:
ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm
-crf
values can go from 4 to 63. Lower values mean better quality.-b:v
is the maximum allowed bitrate. Higher means better quality.
