Dear Michael Kraus,
This does not directly answer your question but may still be of relevance.
Have you considered using Microsoft Clipchamp.
Here is the link: Quick and easy video editor | Clipchamp
Microsoft Clipchamp enables you to easily record what is happening on your screen and export it to a video.
The software has a very modern interface and there is a text-to-speech tool so that you can audially convey instructions to the viewer. The voices are increasingly sounding more-and-more natural.
I hope that this information may provide a little bit of assistance for you, but please consider if it is right for you or not.
Yours sincerely.
James Blythe.
