 An interesting de-shake filter article:
 http://googleresearch.blogspot.in/2012/05/video-stabilization-on-
 youtube.html

 Our deshake filter isn't very efficient with the provided sample (at least
 with the default settings)

 {{{
 clive -f best 'http://www.youtube.com/watch?v=627MqC6E5Yo'
 }}}

 {{{
 ffplay 'Sam and Cocoa shaky original.webm' -vf 'split[a][b];
 [a]pad=iw*2:ih[src]; [b]deshake[filt]; [src][filt]overlay=w'
 }}}

 It would be nice to improve the filter to handle such sample.
