A method of processing a video stream, involves contemporaneously selecting first and second pairs of frames in the video stream with a predetermined period. The second pairs of frames have a longer period than the first pairs. For each of the first and second pairs of frames, there is determined a difference value representing the number of pixels whose value has changed between the first and second frames of the pair. A particular logic level is generated depending on whether this difference value exceeds a predetermined threshold. The generated logic levels are then compared with a decision map to identify cuts in the video stream.
