An image capture device may capture video frames while experiencing motion. The video frames may be stored in a visual track, and rotational positions of the image capture device may be stored in a rotational position track. The visual track and the rotational position track may not be temporally aligned. A looping stabilized view of the view frames and a synchronization adjustment option may be presented on a display. The synchronization adjustment option may enable user modification of timing of the rotational positions stored within the rotational position track. Timing modification of the rotational positions may cause changes in the looping stabilized view, which may be used as feedback on whether the synchronization between the visual track and the rotational position track is being improved or not by the timing modification of the rotational positions.
