Creating a Voice-Over-PowerPoint Presentation

A note to MacOS users:

On many Mac computers, PowerPoint will not save as an MP4 with audio. Here are the steps Mac users need to follow to save their poster presentations as an MP4.

  1. Do not use PowerPoint to record your voice
  2. Instead, use Quicktime player to make a screen recording. (See
  3. Use iMovie to convert the quicktime file to an MP4. (See
  4. Compress the MP4 file if the file is too big.

After following these steps, you may jump ahead to "Uploading a Video to YouTube".

  1. Open your single-slide PowerPoint presentation.  Please make sure to proofread your slide and preview as a slideshow before continuing.
  2. Click the “Slide Show” tab, then click the down arrow on the “Record Slide Show” button and select “Start Recording from Beginning…”.
  3. Make sure both checkmarks are checked in the “Record Slide Show” pop-up, then click “Start Recording”.
  4. Your PowerPoint will open in presentation mode and will begin recording your audio narration. When you are finished narrating, click the “X” in the “Recording” pop-up.
  5. Go to “File” > “Save & Send” > “Create a Video”, then click the “Create Video” button.
  6. In the “Save as type:” drop-down, if you have the option to select “MPEG-4 Video (*.mp4)”, do so and click Save. If you were able to generate and save the .mp4 file in this step, you can skip the section below labeled "Using Handbrake to Convert a .wmv File to .mp4" and go directly to "Uploading a Video to YouTube".
  7. If you do NOT have the option to select “MPEG-4 Video (*.mp4) for the “Save as type:”, you’re probably on an older version of PowerPoint.  Instead, select “Windows Media Video (*.wmv)”.

Using HandBrake to Convert a .wmv File to .mp4

  1. Download the free, open-source video converter, HandBrake,
  2. Install HandBrake as you would other software on your computer and launch it.
  3. Go to “File” > ”Open Source” and select your .wmv file.
  4. On the “Summary” tab, make sure the “Format” shows “MP4”.  You should not need to adjust any other defaults.
  5. Enter a file name for the converted file in the “Save As” box.
  6. Click “Start Encode”.
