A system and method for analyzing and marking a film image for providing a marked film with robust marks which have a high survival rate during, e.g. , unauthorized duplication. The present invention provides the ability to fa cilitate the choosing of ideal locations of marks for marking a film image b y recommending potential marking locations based on the survivability of the mark against different background colors. The system and method provides fo r selecting at least two potential marking areas (400) in at least one frame of the film (302), saturating the at least two potential marking areas in a predetermined color of a mark (310), calculating a root mean square error ( RMSE) of each of the at least two potential marking areas (400) and an area surrounding (401) each potential marking area (312), and determining which o f the at least two potential marking areas has the lowest RMSE (320), i.e., the recommend marking location.
