Combine PowerPoint and Conference Recording

My client had a video recording of himself making a presentation with his PowerPoint slides on the screen behind him. The room lights were on washing out his slides badly. The ask was to convert his PowerPoint to video and edit it together with his conference recording, replacing the washed out slides. I used his slides full-screen in most instances and also placed his slides on the conference room screen when that flowed better. He was very happy with my work and is sending more work my way.
