An electronic device comprises a display to output a video, a user interface for controlling a navigation in the video along a time axis, and a processing device. The processing device is configured, when operating in an operating mode in which an object shown in a plurality of frames of the video is selected by a user input, to determine a magnitude of a speed vector of the object, and to apply a time scaling factor which depends on the determined magnitude of the speed vector of the object to the navigation along the time axis.
