Systems, methods, and non-transitory media are provided for power-efficient image stabilization. An example method can include collecting measurements from a motion sensor, the measurements being based on movement of an image sensor while capturing frames; calculating parameters for counteracting motions in a frame, wherein first parameters are based on the measurements and second parameters are based on some of the measurements; adjusting, in a first stabilization pass of a dual-pass stabilization process, the first frame according to the second parameters; adjusting, in a second stabilization pass of the dual-pass stabilization process, the first frame according to the first parameters; based on a second frame having less motion than the first frame, enabling for the second frame a single-pass stabilization process for both a frame preview process and video record process; and adjusting, in the single stabilization pass, the second frame according to parameters for counteracting motions in the second frame.
