Video narration can make Presentation clearly on PPT?

Last week, my co-founder give me a link to share the solution for the financial software. The sales record his screen. His avatar and the solution on a PPT were recorded in the link. I feel so good and the description of the product is clear. So if your PPT with video narration, do you want to make it? And are u agree the PPT with the video narration is more clear than a single one?
