用这个控制视频录制十秒会不稳定：
  video.StarKinescope(Directory.GetCurrentDirectory() + "\\HR_Video.avi");  //"c://" + System.DateTime.Now.ToString("yyyyMMddHHmmss") + ".avi");
            System.Threading.Thread.Sleep(10000);
            video.StopKinescope();
            video.CloseWebcam(0);
请问大侠有什么好办法能精准的录制十秒的AVI文件。谢谢
