Hyperlapse: smooth first-person action time lapse videos

Some really cool technology in the making: take a helmet cam, go running, climbing, whatever action you’d like to film, and this software will reconstruct a smooth time lapse based on some clever algorithms!

We present a method for converting first-person videos, for example, captured with a helmet camera during activities such as rock climbing or bicycling, into hyperlapse videos: time-lapse videos with a smoothly moving camera.

At high speed-up rates, simple frame sub-sampling coupled with existing video stabilization methods does not work, because the erratic camera shake present in first-person videos is amplified by the speed-up.

Our algorithm first reconstructs the 3D input camera path as well as dense, per-frame proxy geometries. We then optimize a novel camera path for the output video (shown in red) that is smooth and passes near the input cameras while ensuring that the virtual camera looks in directions that can be rendered well from the input.

Next, we compute geometric proxies for each input frame. These allow us to render the frames from the novel viewpoints on the optimized path.

Finally, we generate the novel smoothed, time-lapse video by rendering, stitching, and blending appropriately selected source frames for each output frame. We present a number of results for challenging videos that cannot be processed using traditional techniques.

And this is HOW it works:

About SkyStudioPro

SkyStudioPro is a freeware time-lapse and motion detection application for the Windowsยฎ platform. You can use it to capture time-lapse movies using almost any capture device or web cam. It also features motion detection, you can set it to record movie clips when motion is detected.

Freeware

SkyStudioPro is freeware – you can download and use it free of charge.
There are no limitations to the free version, because there is no commercial version.
Of course, if you want to support the development, you could consider making a donation.

SkyStudioPro version 1.1.0.21 – updated with MovieCompiler

There is a new version of SkyStudioPro available for download: 1.1.0.21

I added a brand new VideoCompiler that you can use to make movies of image sequences. This means that you can now use SkyStudioPro for stop-motion movies as well!
The video settings in VideoCompiler are almost the same as in SkyStudioPro, so you’ll know how to use it right away.

New in this version:

– Upgraded VideoCompiler to version 1.0.0.1
– better GUI and useful hints in VideoCompiler
– preview function in VideoCompiler
– Intergration of VideoCompiler with SkyStudioPro
– better “file closing” when time-lapse movie is saved
