Tutorial Q&A: the tutorial moderator will pause the video occasionally allowing a total of 20-30 questions to be asked “on the fly” by the participants to the tutorial presenter for a total of 25min of tutorial Q&A (per tutorial).



Videos should contain a prominent view of the presentation slides along with audio of the spoken presentation. Optionally videos may contain a shot of the speaker's head for increased engagement. (This shot should be thumbnail-sized and overlayed on the slide images as shown here.) Many presentation software allows recording audio and video directly in the application and can export appropriate video files. Please see the notes below for detailed instructions for PowerPoint and KeyNote. If you use a different application, please see the notes under Other Options.


  1. Follow these instructions to add audio (and optionally video) to your slides.
  2. Follow these instructions to generate a MPEG-4 (.mp4) file from your slides and audio/video.
  3. Alternatively, you can follow this video tutorial which goes through both of these steps. Also, see this video tutorial if you like.

Other Options

  1. Record your screen (and microphone) while giving the presentation. There are effective and free options to do this on LinuxmacOS, and Windows.
  2. As a last resort, and only if you are comfortable directly editing video, you can export your slides as images, record an audio track, and combine the two using software like kdenliveiMovie, or others.
