Abstract

A method and a device for setting a value of an object property in a sequence of metadata frames corresponding to a sequence of video frames is provided. An object is detected (S02) in a plurality of video frames. For a temporally first video frame a first value of an object property is determined (S04) and the object property is set (S06) to have the first value in a metadata frame corresponding to the first video frame. For each subsequent video frame, a subsequent value of the object property is determined (S08) and a deviation is calculated (S12) with respect to a value of the object property that was last set in a metadata frame. If the deviation exceeds a non-zero threshold, the object property is set (S14) to have the subsequent value in a metadata frame corresponding to the subsequent video frame. Otherwise no value of the object property is set (S16) in that metadata frame.
