Instagram released a new separate app yesterday called Hyperlapse, which allows you to make timelapse videos quickly, easily, and with impressive automatic image stabilization technology (meaning that your videos will look smooth and won't betray your shaky, caffeine-addled grip). Today the company, owned by Facebook, released a lengthy blog post describing the technical features that underpin the app. It's pretty geeky, but if you're a programmer, videographer, or just interested in how it all works, have a read.
