Method for encoding video pictures, the method comprising the steps of generating from a video picture a first and a second picture, wherein the second picture has a higher resolution than the first picture and each macroblock in the first picture has a plurality of corresponding macroblocks in the second picture;

  • intra-coding the first picture on macroblock level, wherein macroblocks are predicted and for a first predicted macroblock a prediction direction is determined; and

    intra-coding the second picture on macroblock level, wherein for macroblocks corresponding to said first macroblock, instead of determining the prediction direction, the prediction direction of the first macroblock of the first picture is reused without modification of the direction.
