I am delighted to share with you a few steps that will ensure you are able to produce a quality video that's sharable for whatever you desire. This is a guarantee.
The only commitment on your part is to go through the steps below:
Go to Slide Show on the top ribbon and click
Select Record Slide Show
If your video or mic icons are not active, enable them
When you are ready, click on the red circle to commence recording
Use your usual slide navigation to make your presentation, trying your best to keep a look at the camera
Be as clear as possible and use a natural matter-of-fact diction
When you have done, stop the presentation using the same start icon
You can preview the presentation and discard it if you do not think that it’s good enough and start all over again
When you are happy with the output, click on "End Show" - icon on the extreme left of the screen
Then click on File on the top ribbon and select Export…
Name the file and select MP4 as File Format
Then Export …. This should take some time depending on the size of your video
Your video should be ready for viewing and sharing in your saved location
Here is a video demonstration of all the steps
