OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

Swop

# Install ffmepg (for the screencast) & imagemagick (to optimize the GIF file for web usage)
brew install ffmpeg
brew install imagemagick

# Make the screencast and compress it
ffmpeg -i ScreenFlow.mov -pix_fmt rgb24 output.gif
convert -layers Optimize output.gif output_optimized.gif

# Upload it somewere in the cloud...
# ... and use the file in the desire website. Here's the markdown syntax:

        "log"

Quick, take a guess, what's the first hop latency to your home wireless router?

Below 1ms, right? Yeah, you wish!

Below are results from a quick test on my home router (Linksys E1550). Some lessons learned:

• 3-8ms median
• very different latency tails on different channels (1,6,11)
• running in mixed mode helps tame the long tails (do it, if you can)
• all tests on 2.4Ghz, unfortunately E1550 can't do 5Ghz
