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:
/* | |
1337 Translator | |
"Leet" or "1337" is a popular alternative alphabet used by internet geeks. | |
Create a translator function that takes a string and outputs that string translated to leet | |

A -> @ | |
B -> 8 |
// this is the background code... | |
// listen for our browerAction to be clicked | |
chrome.browserAction.onClicked.addListener(function (tab) { | |
// for the current tab, inject the "inject.js" file & execute it | |
chrome.tabs.executeScript(tab.ib, { | |
file: 'inject.js' | |
}); | |
}); |

Convert .mov/.MP4 to .gif
As a developer, I feel better to upload a short video when I create the pull request to show other viewers what I did in this PR. I tried .mov format directly got after finishing recording screen using Quicktime, however, gif offers preview in most web pages, and has smaller file size.
This is not limited to developer, anyone has this need can use this method to convert the files.
