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.

    • maximum bitrate: 1500Kbps
    • For example, a 12 minutes video should be around 120MB, a 15minutes video should be around 150 MB.

  1. Follow these instructions to add audio (and optionally video) to your slides.
  2. Follow these instructions to generate an MPEG-4 (.mp4) file from your slides and audio/video.
  3. Alternatively, you can follow this video tutorial (How to Make a Video in PowerPoint) which goes through both of these steps. For Keynote, see this video tutorial (Keynote: How To Record & Export High-Quality Videos).


  1. Record your screen (and microphone) while giving the presentation.
  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.
