  Hi Tadas. That string isn't defined, but it does represent the string to set as the 'ActivatableClassId'. I put this together, it isn't super clean, and I'm not sure that I'm doing everything right here, but it does take pictures (note that you need Microphone and Webcam enabled, and if you are using Unity, when you build, you need to build as 'xaml' rather than as 'd3d':

  using UnityEngine;
  using System.Collections.Generic;
  #if !UNITY_EDITOR
  using System;
  using Windows.Media.MediaProperties;
  using Windows.Storage;
  using Windows.Foundation.Collections;
  using Windows.Media.Effects;
  using Windows.Media.Capture;
  #endif
  public class AnotherPicOMatic : MonoBehaviour {
  
  #if !UNITY_EDITOR
      public class VideoMRCSettings : IVideoEffectDefinition
      {
          public string ActivatableClassId
          {
              get
              {
                  return "Windows.Media.MixedRealityCapture.MixedRealityCaptureVideoEffect";
              }
          }
  
          public IPropertySet Properties
          {
              get
              {
                  return _Properties;
              }
          }
  
          private IPropertySet _Properties;
          public VideoMRCSettings()
          {
              _Properties = (IPropertySet)new PropertySet();
              _Properties.Add("HologramCompositionEnabled", true);
              _Properties.Add("RecordingIndicatorEnabled", false);
              _Properties.Add("VideoStabilizationEnabled", false);
              _Properties.Add("VideoStabilizationBufferLength", 0);
              _Properties.Add("GlobalOpacityCoefficient", 0.9f);
          }
      }
  
      MediaCapture captureManager;
      bool open = false;
      async private void InitCamera_Click()
      {
          Debug.Log("Init");
          captureManager = new MediaCapture();
          MediaCaptureInitializationSettings mcsi = new MediaCaptureInitializationSettings();
  
          await captureManager.InitializeAsync();
          IVideoEffectDefinition ved = new VideoMRCSettings();
          await captureManager.AddVideoEffectAsync(ved, MediaStreamType.Photo);
          open = true;
          Debug.Log("Done");
      }
  
      async private void CapturePhoto_Click()
      {
          Debug.Log("Photo");
          ImageEncodingProperties imgFormat = ImageEncodingProperties.CreateJpeg();
  
          // create storage file in local app storage
          StorageFile file = await ApplicationData.Current.LocalFolder.CreateFileAsync(
              "TestPhoto.jpg",
              CreationCollisionOption.GenerateUniqueName);
  
          // take photo
          await captureManager.CapturePhotoToStorageFileAsync(imgFormat, file);
  
          open = true;
          Debug.Log("done");
      }
  
  
  
      // Use this for initialization
      void Start () {
          InitCamera_Click();
      }
  
      // Update is called once per frame
      void Update () {
          if (Time.frameCount % 600 == 0 && open)
          {
              open = false;
              CapturePhoto_Click();
          }
      }
  
  #endif
  }

  Hi Patric
  I wanted to capture MRC video for my demo app. I thought taking an MRC photo as the starting point. I was looking for a way to do it and then came across your this code. I implemented it in the MainPage of my app. In the UI, I have two buttons, one that calls InitCamera_Click() and other that calls CapturePhoto_Click(). Webcam and microphone capabilities are on in appmanifest. While debugging everything looks OK to me. But unfortunately, the picture that is getting saved is a normal photo without the holograms (not an MRC photo). Just to check if the Properties are set OK I changed _RecordingIndicatorEnabled to true. I can then see REC indicator, double checked HologramCompositionEnabled and it was set to true. Could you please let me know if I am missing something or what could be the possibilities that MRC photo is not being saved? (I am not using Unity but VS). Thanks.

  A question for Tadas. Did it work for you? Thanks.

  I double checked and the script is still working in Unity. It might not work from a 2D application.

  I did some digging, and indeed capturing Holograms won't work from a flat/2d app. This is likely to protect users from having other applications recorded. I'm double checking with the teams to be sure.

  Thanks Patrick for a prompt reply. As two or more 2D/flat apps can coexist, It does make some sense what you are saying. At the same time, I am bit confused that MRC from windows device portal can still be able to capture MRC photo/video of multiple 2D applications. May be this is a feature that Microsoft wants to keep close at the moment ;-). Anyway, I will try to make a 3D app using Unity and then try to check if it works or not. I am looking forward for your reply as well after you have checked with the teams.

  Just an update: It did work for a 3D app.
