A computer-implemented method is described including receiving input specifying an image frame from among a series of image frames, and automatically detecting one or more points in the specified image frame that would be suitable for tracking a point in the series of image frames. In addition, a computer-implemented method is described including choosing a first position of a point on a first image frame of a plurality of image frames, and displaying in a bounded region on the first image frame content relating to a second image frame of the plurality of image frames, wherein the content displayed in the bounded region includes a second position of the point at a different time than the first position of the point.
