Instagram's version is more traditional image stabilization. It uses gyroscopic data captured alongside the video to help calculate stabilization. This is all done on the device. Microsoft's version uses post processing on their servers to generate a 3D model of the scene. They then synthesize a new video based on this data. Microsoft's approach is more time intensive and can lead to strange artifacts in the video. But lets them generate a smooth video if, for example, the person wearing the camera glances around quickly mid shot.
