To keep the background steady while looping, Motion Stills has to separate the background from the rest of the scene. As an added benefit, this fixes “pocket shots” (footage of the phone being put back into the pocket). Our approach identifies optimal start and end points, and also discards blurry frames. Short videos are perfect for creating loops, so we added loop optimization to bring out the best in your captures. We obtain further speedup and conserve storage by computing low-resolution warp textures to perform real-time GPU rendering, just like in a videogame.
We achieved a 40x speedup by using techniques such as temporal subsampling, decoupling of motion parameters, and using Google Research’s custom linear solver, GLOP. Our challenge was to take technology designed to run distributed in a data center and shrink it down to run even faster on your mobile phone. Our algorithm uses linear programming to compute a virtual camera path that is optimized to recast videos and bursts as if they were filmed using stabilization equipment, yielding a still background or creating cinematic pans to remove shakiness. We pioneered this technology by stabilizing hundreds of millions of videos and creating GIF animations from photo bursts. All of this works right on your phone, no Internet connection needed.Ī Live Photo before and after stabilization with Motion Stills

You can also tell stories of your adventures by combining multiple clips into a movie montage. With Motion Stills, we provide an immersive stream experience that makes your clips fun to watch and share.
