1. A method for determining a motion vector for a block of a current image in a sequence of video images, each video image being divided into a plurality of blocks, the method comprising the steps of: providing different estimates for a motion vector of the current block, calculating an error value for each of the motion vector estimates based on the current block and a block of a previous image referenced by the motion vector estimate, calculating a further error value for at least one of the motion vector estimates based on the current block and a block in another previous image referenced in accordance with the motion vector estimate, combining said error values calculated based on a single motion vector estimate into a single error value for said selecting step, receiving a film mode indication for the current block, outputting the further calculated error value as said single error value if said film mode indication indicates that the current block is in film mode, and selecting that motion vector estimate as motion vector of the current block having the smallest error value.
