How do I make a professional slide show type video? My wife reads little kid books on YouTube like this. It displays each page in a scrolling pan as she reads it. Our video creator is not longer working with us, so I need to learn how to do it. She had a Mac. I have Windows 10. I'm a software developer, but I don't speak this jargon so I don't even know what to search for. 

I need help.
This video is very simple to do.


Record voice.
Use a proper camera/phone that takes high resolution images (so that when you zoom in the software, it will retain the quality), then take a photo of each page of the book.
Import images and sound into the software.
Do those effects in video which are basically (tilt, pan, zoom-in, zoom-out) mix between them and adjust speed accordingly.


Note: its always better to record sound first, and animate based on that, so that you know how long is each shot and when to cut. 
What software: Personally I only use After Effects and Premier Pro, they are not free but there is a Trial. Check this article for PAID and FREE editing software and try some of them: The best video editing software 2018: paid and free

Basically the effects/transitions mentioned above can be done with any of those softwares, a couple of tutorials should make it possible.
