screencasts on ubuntu have been a pain in the neck. this gist is to document some of the difficulties so I don't have to repeat them.

the idea started when trying to convert a d3.js graphic into animatic gif and found this github program. The term is screen capture

• http://stackoverflow.com/questions/20864874/creating-animated-gif-files-out-of-d3-js-animations

Here is what I came up with

• record the avi with ffmpeg
• converge the ffmpeg to gif with imagemagic

im = io.imread("filename.jpg") 

#crop
