Notice that with &lt;i&gt;shots&lt;/i&gt; I refer to cuts in the camera flow, IIRC hollywood movies have a such a shot cut every 4 seconds as an average (for example when two people talk the camera will move from one person to the other).&lt;p&gt;I remember that I used two techniques for extracting scene cuts:&lt;p&gt;* Difference in the brightness (Y) histogram of the YUV video between frames; when that difference is more than a threshold there&amp;#x27;s a scene cut&lt;p&gt;* Counting the number of Intra macroblocks per frame on an H.264 encoded video; if that number was more than a threshold then there&amp;#x27;s a scene cut</text></comment>
