minimizing the video file size when capturing a video in windows phone 8

I am recording a video in my app and uploading it to a server. The app is working fine for small videos but if the video is longer than 10 seconds the video size becomes very big and the app crashes.

How can I minimize the size of the video? Can I set the resolution? Can I also compress the video?

What else do you recommend I do to make sure the video is not gigantic?

Here is my code : 

Public Sub InitializeVideoRecorder()
        If captureSource Is Nothing Then
            ' Create the VideoRecorder objects.
            captureSource = New CaptureSource()
            fileSink = New FileSink()

            videoCaptureDevice = CaptureDeviceConfiguration.GetDefaultVideoCaptureDevice()

            ' Add eventhandlers for captureSource.
            AddHandler captureSource.CaptureFailed, AddressOf OnCaptureFailed

            ' Initialize the camera if it exists on the device.
            If videoCaptureDevice IsNot Nothing Then
                ' Create the VideoBrush for the viewfinder.
                videoRecorderBrush = New VideoBrush()
                videoRecorderBrush.SetSource(captureSource)

                ' Display the viewfinder image on the rectangle.
                viewfinderRectangle.Fill = videoRecorderBrush

                ' Start video capture and display it on the viewfinder.
                captureSource.Start()

                ' Set the button state and the message.
                UpdateUI(ButtonState.Initialized, "")
            Else
                ' Disable buttons when the camera is not supported by the device.
                UpdateUI(ButtonState.CameraNotSupported, "A camera is not supported on this device.")
            End If
        End If
End Sub

To reduce the video size we can make the resolution as much low.The code 

VideoCaptureDevice webcam = CaptureDeviceConfiguration.GetDefaultVideoCaptureDevice();

 int videoformatcount = webcam.SupportedFormats.Count(); //We will get the avilable video format

  if (videoformatcount > 0)
             {
                var Temp = webcam.SupportedFormats;

                VideoFormat objVideoFormat = Temp[videoformatcount - 1];

                webcam.DesiredFormat = new VideoFormat(PixelFormatType.Format8bppGrayscale, objVideoFormat.PixelWidth, objVideoFormat.PixelHeight, 1);
            }

captureSource.VideoCaptureDevice = webcam;

It will help you.The video must be in very low resolution(Available).
