To record a PowerPoint presentation with video:

1. Open the PowerPoint presentation that you want to record.
2. Click the “Slide Show” tab at the top of the window.
3. Click the “Record Slide Show” button in the “Set Up” group.
4. In the “Record Slide Show” window, select the “Record from Beginning” option.
5. Click the “Start Recording” button.
6. The slide show will start and you can speak while the presentation is playing.
7. To stop the recording, click the “Stop Recording” button on the PowerPoint control bar at the top of the screen.

The recorded slide show will be saved as a video file in the same folder as the original PowerPoint presentation. You can then share the video file with others or upload it to a video sharing site like YouTube.
