Hyperlapse

Hyperlapse

Last week I had my sister visit me in Berlin and I used the GoPro to record while we rode our bikes. It’s not that I intended to use that footage for anything special further on, but I’m now thinking I will keep it and try some hyperlapse on them.

Hyperlapse is the new trend that extends time lapse shooting. It is based on single still frames instead of just speeding up a video, plus the camera is also moving, so more movement is actually involved in between shots. It’s like a time lapse inside of a time lapse… — a meta time lapse video!

It was first used to incorporate HDR into motion pictures by simply mounting together many different HDRed pictures into a video, but it’s use has since evolved to achieve other amusing effects. Check out this recently published video by Rob Whitworth (who already recorded the famous flow motion video for Barcelona as well) to see what hyperlapse looks like.

How to achieve a simple hyperlapse video

If you’ve been toying around with time-lapse photography and want a fun photography project for the weekend, this quick hyperlapse how-to from the fun folks over at DigitalRevTV has you covered.
Kai wisely teams up with expert Patrick Cheung to let you know how it is done.

Google Maps hyperlapsing

But handheld pans are not the only stuff hypelapses are made of. The guys at Teehan Lax have developed a JavaScript script to help you through the process of hyperlapsing your way to work by making use of Google Maps’ API. In short, you can use this website were they present their working plugin so that you can easily situate points A and B on a map and create your own hyperlapse video using Google Maps’ images. Isn’t that creative?

First person stabilisation hyperlapse

Here’s where my GoPro story comes in. There’s a bunch of guys at Microsoft Research in Redmond (WA) working on an algorithm to stabilise high speed first person camera footage. When filmed though one of these, attached to your forehead or chest, the world around you becomes so shaky that high speed videos are almost unbearable to watch and irritating, and stabilising is difficult as hell. Johannes Kopf, Michael Cohen and Richard Szeliski promise it will reach the public as an app in a near future.

The technology involved recreates a 3D version of the world described in the footage, placing each frame where it would correspond in space and tracking the camera movement. This real camera path will be then simplified to a spline that would take the viewer through a new, smoother, path by repainting the surroundings via patches from the matching available frames. Lovely.

Here’s the video that accompanied their SIGGRAPH paper this month, to show you better what they’re doing:

Summery hyperlapse

And finally, as a bonus, here’s a sweet as pie, happy coloured, hyperlapse video to enhance our summer afternoons.
