Zusammenfassung:	A method (and corresponding entity, system, computer program) is provided for determining a positioning indication for positioning a graphic element indicating a position at which a graphic element is to be overlaid to a video stream comprising a first image and a second image. The method comprises the steps of: - determining (S10) at least one probe area (S1,i) for the first image (Ii) of said video stream, and at least one corresponding probe area (S1,i+N) for the second image (Ii+N) of said video stream; determining (S20) a shift direction indicating a direction according to which the at least one corresponding probe area (Si,i+N) of said second image (S1,i+N) has shifted with respect to the at least one probe area (S1,i) of said first image (Ii); - determining (S30) the positioning indication (p) on the basis of said shift direction (d).
