iOS Hyperlapse's secret best feature: fixing your shaky hands

Hyperlapse, Instagram's standalone video app that debuted this past August, is touted for its ability to make dead simple time lapses in your videos. But if you really want to enjoy the best feature of Hyperlapse, don't speed up the footage. The result is some of the smoothest video I've ever seen from a phone — the kind of stuff that could otherwise take thousands of dollars in professional equipment to achieve comparable results. Student art films, video of you running next to your kid while they are heading down the field to score, and more will never be the same again.

Unstabilized is unedited video while running. The video following showing the 1x bar is when Hyperlapse uses it's software on the same video to smooth it out.

Instagram calls its technology Cinema Stabilization, and outlined the overall idea in a blog post. Whereas a tool like Adobe's warp stabilization has to calculate the shake using only pixels in the footage, Hyperlapse has the benefit of gyroscope data — basically, it knows how badly your hands were shaking the whole time, and uses that information to keep the frame as still as possible. The footage is shot in 1080p but outputs in 720p, with the extra footage used as a "buffer," sacrificed in the name of stabilization. 

There is a hidden menu for changing the output resolution. Hyperlapsers can tap into their iPhone’s full potential by accessing the hidden ‘Labs’ menu that lets you tweak everything from your recording resolution, frame rate, speed multiplier options and even the sound levels.

Here’s how to access Hyperlapse’s secret settings:

Step 1: Open Hyperlapse
Step 2: Tap the screen four times with four fingers (it may take a few attempts).
Step 3: Adjust resolution to 1080p.
Step 4: Enable Hyperlapse EXTREME – adds 24x and 40x speed multipliers
Step 5: Tap done.


The end result is especially impressive considering what we have to otherwise do to get that smooth a picture on our much pricier video cameras: no tracks, jibs, cranes, or crazy vets required. And the best part is that it's assuredly just the most streamlined, mainstream example of what's to come for smartphone video — which, let's be honest, it's mostly how people take video these days.
