Abstract: A method prunes a prediction-coded video sequence and a corresponding pruning device. The pruning method comprises: obtaining one or more global motion values for the video sequence, wherein each global motion value represents an amount of motion in a scene depicted by a set of successive image frames in the video sequence; for a set of successive image frames having a global motion value being below a global motion threshold, identifying an immediately following group of pictures, GOP; obtaining a skip frame having the same frame configuration as the image frames of the identified GOP; replacing the initial intra frame of the identified GOP with the obtained skip frame; and configuring the skip frame and the remaining image frames of the identified GOP to form a continuation of a frame numbering of an immediately preceding GOP.
