Abstract
A video capture device may include multiple cameras that simultaneously capture video data. The video capture device and/or one or more remote computing resources may perform video stabilization to the video data to reduce unwanted camera shake. The video capture device may include one or more motion sensors that track the motion of the video capture device. Using the motion data, video stabilization algorithms can be executed on a first video stream to calculate stabilizing adjustments for the video stream. The stabilization adjustments can then be used to stabilize a second video stream due to the fixed positioning of a first camera that captured the first video stream and a second camera that captured the second video stream. The video capture device and/or the remote computing resources may stitch together the first and second video streams to generate a digitally stabilized panoramic video.
