Resize encoded video by c# codes SDK

Question

I am using EE 4 Pro  and a live job in C# code as LiveJob job = new LiveJob();  ... to stream video.

I'd like to know how to use C# source codes with EE 4 Pro SDK to resize encoded video during encoding process. 

For example, if I have an original video whose dimensions are 6 in X 9 in, I would like to know how use C# source codes to resize encoded video.

In details, in scaled smaller versions  with rates of 1/6, 1/3, and 1/2 , I will get  1 in X 1.5 in; 2 in X 3 in ; and  3 in X 4.5 in encoded videos, and they are saved out as 3 encoded video files.

Or in scaled bigger versions with rate of 1.5 and 2, I will get  9 in X 13 in;  and 12 in X 18 in coded videos, and they are saved out as 2 encoded video files.

Thank you.

Here is my version of resizing, but I'm doing it with VOD videos. But I don't thing there will be a big difference.

                    MP4OutputFormat mp4Format = new MP4OutputFormat();
                    mp4Format.VideoProfile = new Microsoft.Expression.Encoder.Profiles.HighH264VideoProfile();
                    mp4Format.AudioProfile = new Microsoft.Expression.Encoder.Profiles.AacAudioProfile();
                    mp4Format.VideoProfile.AspectRatio = new System.Windows.Size(16, 9);
                    mp4Format.VideoProfile.AutoFit = true;
                    mp4Format.VideoProfile.Size = new System.Drawing.Size(1920, 1080);
                    mp4Format.VideoProfile.Bitrate = new Microsoft.Expression.Encoder.Profiles.VariableUnconstrainedBitrate(6000);

                    mediaItem.VideoResizeMode = VideoResizeMode.Letterbox;
                    mediaItem.OutputFormat = mp4Format;
