Hi Willem,

This is not a standard answer to your question, but the best way I could think of is to work on a 4:3 powerpoint. Set the background as black, and insert a frame of 16X9 ratio in your Master slide. You you may work within this frame.

When publishing, you may set the background color of the presenter file to black so that the ratio looks like 16:9.

Here is a preview -

A little more idea - You will notice that there is a little extra black space at the bottom part. To make the course look more like a film, you may add here the audio script of the course, to make it look like sub titles.

I have attached the Power Point slide I created. Do use if it is helpful.
