In various embodiment of the present invention, the difference of disparity between subtitles in stereoscopic content along time is restrained by a function of time and disparity. This guarantees that two consecutive subtitles will have similar disparity if they are close in time. More specifically, a method for the positioning of subtitles in stereoscopic content includes estimating a position for a subtitle in at least one frame of the stereoscopic content and restraining a difference in disparity between subtitles in at least two frames by a function of time and disparity. In such an embodiment, the estimating can include computing a disparity value for the subtitle using a disparity of an object in a region in the at least one frame in which the subtitle is to be inserted. The subtitle can then be adjusted to be in front of or behind the object.
