Moving Mediasite Presentations to Microsoft Stream

What it is 

If there is material on the Mediasite server you would like to retain, it is often possible to migrate that to another media delivery service, like Microsoft Stream, which is part of the Office 365 suite of tools available to the campus community. Note that repurposing Mediasite presentations may take longer than the original recordings playback times, so you we encourage you to evaluate the value of the preserved recordings and consider not repurposing them or taking this an opportunity to update and improve them by simply rerecording them in the Stream environment. 

The Process 

The basic process will look like this: 

  1. Find the presentations you would like to migrate and continue using. 
  2. Download them to your local computer. Note that file size is proportional to the length of the presentations, so longer ones will be larger. This means they will take longer to download. This may create challenges both for your home bandwidth and your ability to store the files on your local computer. 
  3. Examine the downloaded files to see what kind of presentation you recorded. Mediasite was capable of recording the screen, audio, webcam, and presentation slides as separate items, and then combining them for delivery in a web page. 
  4. The next step will depend on what kind of presentation you created: 
    1. Screencast with audio or uploaded movies – move single mp4 file to MS Stream. 
    2. Screencast with video play the presentation back in real-time while recording it with Camtasia. 
    3. Slides with audio play the presentation back in real-time while recording it with Camtasia. 
    4. Slides with audio and webcam - play the presentation back in real-time while recording it with Camtasia. 
  5. Export Camtasia project as mp4 video file. 
  6. Import result into MS Stream. 

 Important Considerations 

Migrating a Mediasite presentation with slides will require playing them back and rerecording them in real-time, i.e. a 60-minute presentation will take 60 minutes to rerecord. 

 Materials shared using Microsoft Stream are only viewable by those in the CSUSM domain, i.e. those with a campus login. If you need to deliver to an audience outside of CSUSM, contact us at for an alternative delivery method such as YouTube.

Determining What Kind of Presentation It Is

There are five basic kinds of Mediasite presentation:

  • Uploaded movies – these are video files you simply uploaded into Mediasite. These are the simplest to migrate, since there is just a single movie file to move over. Skip ahead to the section below entitled Uploading a Video-Only Presentation to MS Stream.

The other four types are recordings you created by recording yourself:

  • Screencast with audio
  • Screencast with video
  • Slides with audio
  • Slides with audio and webcam 

For these proceed to the next section: Playing and Recording a Slide-based Presentation for Repurposing.

Playing and Recording a Slide-based Presentation for Repurposing

If you would like to retain a Mediasite presentation for use after Mediasite is no longer available, there are two routes:

  • If the presentation is video-only, i.e. containing no slides or other info, skip ahead to the next section Uploading a Video-Only Presentation to MS Stream.
  • If the presentation contains slide material, then it will need to played out and recorded from your screen in real-time.
  1. Have the presentation open and ready to play.
  2. Adjust the Mediasite display settings so that all media types are visible.
  3. Launch Camtasia and get it ready to record. When it launches you will see the setup window.Camtasia recording window
  4. You need to record two things – part of the screen and system audio. Turn those buttons on and turn the others off.
  5. Pop up the recording area menu on the left – the one that says Color LCD in my example - and choose Region. This will allow you to select the area of the screen to be recorded.Choose what to record
  6. Click and drag from the upper left to the lower right to draw a rectangle around the display area of the the presentation. Click on Ok at the bottom of the selected area. In this example you can see I have selected the display area in this Mediasite as I plays in a browser window, and that this selected area is reflected in the thumbnail in the Region at the bottom. See where it says 2482 x 1408 – that’s the size of the selected recording area in pixels.Camtasia recording example
