            capturer.OutputWidth = 640;
            capturer.OutputHeight = 480;

	    // WMV and WEBM output use WMVVideoBitrate property to control output video bitrate
   	    // so try to increase it by x2 or x3 times if you think the output video are you are getting is laggy
	    // capturer.WMVVideoBitrate = capturer.WMVVideoBitrate * 2;

            
  	    // uncomment to set Bytescout Lossless Video format output video compression method
	    // do not forget to set file to .avi format if you use Video Codec Name

	// IMPORTANT: if you want to check for some code if need to stop the recording then make sure you are 
	// using Thread.Sleep(1) inside the checking loop, so you have the loop like
	// Do {
	// Thread.Sleep(1) 
	// }
	// While(StopButtonNotClicked);
