Although it is getting rarer for these situations to exist, Google announced today that an app they had developed exclusively for the iOS platform is now available for Android devices running Android v5.1 or later. The app is called Motion Stills and it accomplishes a couple different goals. First, it can be used to create short form video clips by compressing longer videos using a feature called Fast Forward. Second, Motion Stills incorporates some advanced algorithms and code to significantly stabilize video clips. The new Motion Stills app is now available in the Play Store.
One of the steps that Google undertook in making Motion Stills available on Android was to redesign the existing video processing pipeline used in the iOS app. The new process computes motion metadata and stabilizes video immediately using low resolution texture maps. This can then be applied by a GPU in real-time during playback so that stabilizing transformations are completed on the original video during playback instead of creating a whole new video file that has been stabilized. This stabilized video can then be quickly converted and share as a GIF file.
For the Fast Forward feature, Google uses denser I-frame spacing than is typical to improve the efficiency of seek and playback of video content. This information can then be used to process up to a full minute of video on a smartphone with the ability to adjust playback speed from 1x to up to 8x. Google says they also use several other optimizations to keep the resulting video smoother and better looking.
Whether sped up or just stabilized, the Motion Stills app will also do things like automatically loop the resulting image. Google also says it uses a new trimming algorithm to avoid pocket shots or unusual camera shakes.
The Motion Stills app is available now in the Google Play Store and you can grab it using the link below. While this is currently a standalone app, Google says it is also an experiment for developers to gather feedback on useful and fun tools that may be incorporated into other Google products. In the case of Motion Stills, the company could decide to add the stabilization and fast forward technology to their Google Photos app.
