WP8.1 beta version "Hyperlapse" appears in the App Store

In August last year, Microsoft Research announced the Hyperlapse project. Hyperlapse is a video algorithm that can convert bumpy and shaky videos into smooth first-person demonstration videos. At that time, Microsoft said that it would launch Windows applications based on Hyperlapse technology as soon as possible. Today, the WP8.1 internal beta version of the "Hyperlapse" application has quietly appeared in the Windows Phone App Store.

This application currently does not support downloading and use by users other than Microsoft's internal testing team. On the Windows platform, Hyperlapse will be used to stabilize videos recorded by action cameras (such as GoPro), but the mobile version of the "Hyperlapse" application is obviously more exciting. The official blog of Microsoft Research introduces the working principle of Hyperlapse technology:

First, based on the original video, the algorithm restores the movement trajectory of the camera during the shooting process, as well as the distance and distance of the camera relative to the objects in each frame. angle. Then, it optimizes and simulates a camera motion trajectory that is smoother than the original, and captures and splices pixels from the original video to reconstruct the scene under this new trajectory, thereby outputting a stable and smooth time-lapse photography effect. video.

Currently, Instagram has launched an application also called "Hyperlapse" for the iPhone. The calculation mechanism of this application is similar to Microsoft's Hyperlapse technology, which can significantly weaken the video jitter phenomenon. The processing effect on the iPhone is quite good. Therefore, we also believe that Microsoft’s upcoming Windows Phone 8.1 version of “Hyperlapse” can compete with similar applications on other platforms.
