Xamarin.Android Record Video - Quality Poor - xamarin

Question

I'm using the following Xamarin tutorial https://developer.xamarin.com/recipes/android/media/video/record_video/
I can successfully record video and audio however the quality is not very good. Can anyone suggest/explain how I can increase the quality please?
I know the device can record in higher quality because the native camera app record in much higher quality.
EDIT here is my code so far
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.RecordVideo);
var record = FindViewById<Button>(Resource.Id.Record);
var stop = FindViewById<Button>(Resource.Id.Stop);
var play = FindViewById<Button>(Resource.Id.Play);
var video = FindViewById<VideoView>(Resource.Id.SampleVideoView);
var videoPlayback = FindViewById<VideoView>(Resource.Id.PlaybackVideoView);
string path = Android.OS.Environment.ExternalStorageDirectory.AbsolutePath + "/test.mp4";
if (Camera.NumberOfCameras < 2)
{
Toast.MakeText(this, "Front camera missing", ToastLength.Long).Show();
return;
}
video.Visibility = ViewStates.Visible;
videoPlayback.Visibility = ViewStates.Gone;
_camera = Camera.Open(1);
_camera.SetDisplayOrientation(90);
_camera.Unlock();
recorder = new MediaRecorder();
recorder.SetCamera(_camera);
recorder.SetAudioSource(AudioSource.Mic);
recorder.SetVideoSource(VideoSource.Camera);
recorder.SetOutputFormat(OutputFormat.Default);
recorder.SetAudioEncoder(AudioEncoder.Default);
recorder.SetVideoEncoder(VideoEncoder.Default);
//var cameraProfile = CamcorderProfile.Get(CamcorderQuality.HighSpeed1080p);
// recorder.SetProfile(cameraProfile);
recorder.SetOutputFile(path);
recorder.SetOrientationHint(270);
recorder.SetPreviewDisplay(video.Holder.Surface);
record.Click += delegate
{
recorder.Prepare();
recorder.Start();
};
stop.Click += delegate
{
if (recorder != null)
{
video.Visibility = ViewStates.Gone;
videoPlayback.Visibility = ViewStates.Visible;
recorder.Stop();
recorder.Release();
}
};
play.Click += delegate
{
video.Visibility = ViewStates.Gone;
videoPlayback.Visibility = ViewStates.Visible;
var uri = Android.Net.Uri.Parse(path);
videoPlayback.SetVideoURI(uri);
videoPlayback.Start();
};
}

I don't see the example specifying the CamcorderProfile anywhere so you might want to start from that. It's possible that the default framerate, bitrate and video frame size are lower than you'd expect. I'm not an a computer right now but try to set the profile to for example QUALITY_1080p using the SetProfile method in MediaRecorder.
You need to set the profile after setting the video and audio sources but before calling SetOutputFile method.
