Screencapture and animated gifs

I say "animated gif" but in reality I think it's irresponsible to be serving "real" GIF files to people now. You should be serving gfy's, gifv's, webm, mp4s, whatever. They're a fraction of the filesize making it easier for you to deliver high fidelity, full color animation very quickly, especially on bad mobile connections. (But I suppose if you're just doing this for small audiences (like bug reporting), then LICEcap is a good solution).

Capturing (Easy)

Launch quicktime player
do Screen recording

Get Instagram Images via JavaScript

Get API Info

You will need the user_id from the user. This is difficult to discover at Instagram but easy from this site http://jelled.com/instagram/lookup-user-id

I used http://jelled.com/instagram/access-token for the next few steps

You will also need an access token which ends up being difficult to obtain. Log into the account and go to their Developer Page.

Installing

Install FFmpeg with homebrew. You'll need to install it with a couple flags for webm and the AAC audio codec.

brew install ffmpeg --with-libvpx --with-libvorbis --with-fdk-aac --with-opus
