Presentation recording process using PowerPoint

General tips:

● Use 16:9 as slide size (see instructions with screenshots below).

Simplify your presentation: avoid using too much text on one slide to make sure it could be read even by someone with poor connection.

● While recording voiceover for your presentation, make sure you use a headset (headphones + microphone) to ensure the best audio quality.

● When exporting your presentation with recording, make sure the final format is MP4.

● Please check your exported video presentation to verify that the video is playing smoothly, audio is clear and the slides readable.


Step 1: Choosing correct slide size

Design tab > Slide size > Widescreen (16:9)









Step 2: Including a video to your presentation

Insert tab > Video > Video on My PC















Resize the video to fit your design, content, and layout.

Select the video and use the options in the “Playback” menu to set the video to playback.

















Select either “Automatically” (begin the video as soon as the slide loads) or “In Click Sequence” (begin when you click next within the slide).










Step 3: Recording your narration


Video guidelines:







Record narration and timings

1. Select Slide Show > Record Slide Show .

2. Choose from two options:

Record from Current Slide – to record from a specific slide

i. Record from Beginning – to record from the beginning of a presentation.















3. When you’re ready, select Record and start speaking.














To record from a specific slide, go to it, and then select Record.


Note: Narration won’t record when slide transitions happen so let these play first before you start speaking.


Manage microphone and camera input

On the upper right corner, you will see buttons that navigate you to select the appropriate microphone and camera to record your presentation. It is always recommended to use a headset (headphones + microphone) to ensure better sound quality. You should check these settings before you start recording.













Manage narration and timings

There are different ways to manage recordings in your presentation:

·      Pause – to pause a recording

·      Stop – to end a recording

·      Replay – to replay a recording

·      Pen, Highlighter, or Eraser – use the pen, highlighter, or eraser tools to mark up your recording
