How about convert the PowerPoint to Video?



Wondershare PPT2Video I think

That's not a bad idea, but we were hoping to incorporate a person speaking in the video too, preferably using a green screen, since that's more engaging than just watching still slides. Is there a program that can do that?

That would be completely different, I would say!

As to a software solution that would incorporate the green screen technology with PowerPoint?? First you'd need the green screen, then a good camera and then the software - and that, I think, would be a professional app, at a professional price!!

If you were to try your local college or FE facility and go to their media department, they may have the green screen technology for rental!

I took your advice on the professional software route and did some Googling. I found a program called Instant Video Presenter - it seems like it does everything I mentioned, it includes a green screen, and is much more affordable than most other video options. There's a free 30-day trial too.
