Abstract

A method for encoding video is disclosed. The method comprises the steps of receiving (S02) information representative of pixels in a current digital image frame of a video to be encoded, calculating (S03) a group value for each group of neighboring pixels based on the received information, accumulating (S04) group values of corresponding groups of pixels in a first sequence of frames to form a first accumulation of accumulated group values, accumulating (S05) group values of corresponding groups of pixels in a second sequence of frames to form a second accumulation of accumulated group values, wherein the second sequence includes frames captured over a longer period of time than the first sequence, comparing (S06) accumulated group values of the first accumulation with accumulated group values of the second accumulation, calculating (S07) a global change value based on the comparison, setting (S08) a GOP length based on the global change value; and encoding (S09) the current image frame as an intra-frame or inter-frame based on the GOP length. An encoder system for encoding video is also disclosed.
